GitClub-Flutter

一、Flutter的简介

Flutter是谷歌最早于2015年Dart开发者峰会亮相并推出的移动UI框架,可以快速在iOS和Android上构建高质量的原生用户界面,目的是能够以每秒120帧的速度持续渲染,基于该特性Flutter正在被用作一些游戏开发。Flutter可以与现有的代码一起工作,被越来越多的开发者和组织使用,并且Flutter是完全免费且开源的,去年12月份Flutter1.0稳定版正式推出。Flutter中文网

二、GitClub的简介

GitClub是一款分享一些优秀的、新的Android开源库,一些重要的Android类的技术文章,以及一些程序开发业内的重要新闻,让感兴趣的伙伴利用零碎时间,如挤地铁、蹲大号、等女朋友的时候刷刷我们的小程序。当然以后也会增加其他开发语言的受众群体,java,javaEE,javaScript,C/C++,IOS,Html,PHP,Physon等等。

三、主要内容

1、Flutter引入第三方库的pub仓库地址(https://pub.dartlang.org/packages/)
2、个人开发观点

首先个人觉得国内使用Flutter开发的公司并不算多,所以很多技术不够成熟,从而碰到开发中一旦碰到问题,有一部分百度的话是可以解决的,但是很多时候百度搜索到的东西并不是自己想要的(只是个人观点),而国外对于Flutter的开发是相对比较成熟的,所以Google搜索是非常有必要的,本人在项目中遇到的多个问题最终都是Google到的结果。Flutter作为Google推出的跨平台方案,第一个优势就是其性能和UI效果可以说无限接近原生, 再其次就是其超强的跨平台能力,大家可以看下面的Flutter SDK中的图,

这是几个意思啊,好吓人啊,难道支持所有平台?呵呵,自己去体会吧,这个API已经可以看出Google的野心。第一个TargetPlatform中的意思其实是提供判断当前手机系统的平台版本,以便于开发者进行差异化处理,后一个嘛,要等,现在我还不敢把所有的事情说死,毕竟像Google这种公司说不定炒的很火的产品,第二天就宣布不做了,这个也是常事,现在把事情说的太死,以后万一没火起来岂不是自己打脸。言归正传,使用Flutter开发首先必须要安装Flutter的SDK,以及配置一些环境,这个自行搜索,今天我们的主要内容是分享项目GitHub地址

3、Flutter和Fuchsia系统的关系

既然主角是Flutter那就顺带介绍下Fuchsia系统,目前移动操作系统最流行的莫过于Android和iOS两个阵营,而Fuchsia与两者完全不同,Android是基于Linux内核,所以内存管理机制与Linux很相似,这就是Android始终存在一个弊端,也就是JVM的存在,虚拟机的存在是导致Android手机负载过重的一个根本问题,可以想象一下当你打开一个应用程序,系统会自动为该程序创建并维护一个虚拟机,当应用创建过多的时候,运行内存占用会越来越大,这就是大家所经常所说的为什么Android手机4G的运行内存为何还敌不过iOS 2G的内存?这就是体现iOS比Android稳定的一个例子了(勿喷,本人也是Android阵营)。还有一个因素就是Android当今市场碎片化太过严重,几乎国内安卓手机都用厂商的定制ROM,Google想缩紧权限也是有心无力,那么Fuchsia的出现就是为了解决这些弊端,而且Fuchsia如今已被证实将支持兼容Android应用,并且Fuchsia 是使用 Flutter SDK 开发的,所以 Fuchsia 的一部分可以在 Android 设备上运行。不过Android的小伙伴也不必过于担心,针对Fuchsia系统的正式出现到普及还未可知,但技多不压身,学习并入手Flutter还是很有必要的。

四、效果展示

先来看一下效果页面(直接完全基于Flutter脚手架开发,没有专业UI设计,UI不够完美敬请谅解)。

Academic Free License (“AFL”) v. 3.0 This Academic Free License (the "License") applies to any original work of authorship (the "Original Work") whose owner (the "Licensor") has placed the following licensing notice adjacent to the copyright notice for the Original Work: Licensed under the Academic Free License version 3.0 1) Grant of Copyright License. Licensor grants You a worldwide, royalty-free, non-exclusive, sublicensable license, for the duration of the copyright, to do the following: a) to reproduce the Original Work in copies, either alone or as part of a collective work; b) to translate, adapt, alter, transform, modify, or arrange the Original Work, thereby creating derivative works ("Derivative Works") based upon the Original Work; c) to distribute or communicate copies of the Original Work and Derivative Works to the public, under any license of your choice that does not contradict the terms and conditions, including Licensor’s reserved rights and remedies, in this Academic Free License; d) to perform the Original Work publicly; and e) to display the Original Work publicly. 2) Grant of Patent License. Licensor grants You a worldwide, royalty-free, non-exclusive, sublicensable license, under patent claims owned or controlled by the Licensor that are embodied in the Original Work as furnished by the Licensor, for the duration of the patents, to make, use, sell, offer for sale, have made, and import the Original Work and Derivative Works. 3) Grant of Source Code License. The term "Source Code" means the preferred form of the Original Work for making modifications to it and all available documentation describing how to modify the Original Work. Licensor agrees to provide a machine-readable copy of the Source Code of the Original Work along with each copy of the Original Work that Licensor distributes. Licensor reserves the right to satisfy this obligation by placing a machine-readable copy of the Source Code in an information repository reasonably calculated to permit inexpensive and convenient access by You for as long as Licensor continues to distribute the Original Work. 4) Exclusions From License Grant. Neither the names of Licensor, nor the names of any contributors to the Original Work, nor any of their trademarks or service marks, may be used to endorse or promote products derived from this Original Work without express prior permission of the Licensor. Except as expressly stated herein, nothing in this License grants any license to Licensor’s trademarks, copyrights, patents, trade secrets or any other intellectual property. No patent license is granted to make, use, sell, offer for sale, have made, or import embodiments of any patent claims other than the licensed claims defined in Section 2. No license is granted to the trademarks of Licensor even if such marks are included in the Original Work. Nothing in this License shall be interpreted to prohibit Licensor from licensing under terms different from this License any Original Work that Licensor otherwise would have a right to license. 5) External Deployment. The term "External Deployment" means the use, distribution, or communication of the Original Work or Derivative Works in any way such that the Original Work or Derivative Works may be used by anyone other than You, whether those works are distributed or communicated to those persons or made available as an application intended for use over a network. As an express condition for the grants of license hereunder, You must treat any External Deployment by You of the Original Work or a Derivative Work as a distribution under section 1(c). 6) Attribution Rights. You must retain, in the Source Code of any Derivative Works that You create, all copyright, patent, or trademark notices from the Source Code of the Original Work, as well as any notices of licensing and any descriptive text identified therein as an "Attribution Notice." You must cause the Source Code for any Derivative Works that You create to carry a prominent Attribution Notice reasonably calculated to inform recipients that You have modified the Original Work. 7) Warranty of Provenance and Disclaimer of Warranty. Licensor warrants that the copyright in and to the Original Work and the patent rights granted herein by Licensor are owned by the Licensor or are sublicensed to You under the terms of this License with the permission of the contributor(s) of those copyrights and patent rights. Except as expressly stated in the immediately preceding sentence, the Original Work is provided under this License on an "AS IS" BASIS and WITHOUT WARRANTY, either express or implied, including, without limitation, the warranties of non-infringement, merchantability or fitness for a particular purpose. THE ENTIRE RISK AS TO THE QUALITY OF THE ORIGINAL WORK IS WITH YOU. This DISCLAIMER OF WARRANTY constitutes an essential part of this License. No license to the Original Work is granted by this License except under this disclaimer. 8) Limitation of Liability. Under no circumstances and under no legal theory, whether in tort (including negligence), contract, or otherwise, shall the Licensor be liable to anyone for any indirect, special, incidental, or consequential damages of any character arising as a result of this License or the use of the Original Work including, without limitation, damages for loss of goodwill, work stoppage, computer failure or malfunction, or any and all other commercial damages or losses. This limitation of liability shall not apply to the extent applicable law prohibits such limitation. 9) Acceptance and Termination. If, at any time, You expressly assented to this License, that assent indicates your clear and irrevocable acceptance of this License and all of its terms and conditions. If You distribute or communicate copies of the Original Work or a Derivative Work, You must make a reasonable effort under the circumstances to obtain the express assent of recipients to the terms of this License. This License conditions your rights to undertake the activities listed in Section 1, including your right to create Derivative Works based upon the Original Work, and doing so without honoring these terms and conditions is prohibited by copyright law and international treaty. Nothing in this License is intended to affect copyright exceptions and limitations (including “fair use” or “fair dealing”). This License shall terminate immediately and You may no longer exercise any of the rights granted to You by this License upon your failure to honor the conditions in Section 1(c). 10) Termination for Patent Action. This License shall terminate automatically and You may no longer exercise any of the rights granted to You by this License as of the date You commence an action, including a cross-claim or counterclaim, against Licensor or any licensee alleging that the Original Work infringes a patent. This termination provision shall not apply for an action alleging patent infringement by combinations of the Original Work with other software or hardware. 11) Jurisdiction, Venue and Governing Law. Any action or suit relating to this License may be brought only in the courts of a jurisdiction wherein the Licensor resides or in which Licensor conducts its primary business, and under the laws of that jurisdiction excluding its conflict-of-law provisions. The application of the United Nations Convention on Contracts for the International Sale of Goods is expressly excluded. Any use of the Original Work outside the scope of this License or after its termination shall be subject to the requirements and penalties of copyright or patent law in the appropriate jurisdiction. This section shall survive the termination of this License. 12) Attorneys’ Fees. In any action to enforce the terms of this License or seeking damages relating thereto, the prevailing party shall be entitled to recover its costs and expenses, including, without limitation, reasonable attorneys' fees and costs incurred in connection with such action, including any appeal of such action. This section shall survive the termination of this License. 13) Miscellaneous. If any provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable. 14) Definition of "You" in This License. "You" throughout this License, whether in upper or lower case, means an individual or a legal entity exercising rights under, and complying with all of the terms of, this License. For legal entities, "You" includes any entity that controls, is controlled by, or is under common control with you. For purposes of this definition, "control" means (i) the power, direct or indirect, to cause the direction or management of such entity, whether by contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the outstanding shares, or (iii) beneficial ownership of such entity. 15) Right to Use. You may use the Original Work in all ways not otherwise restricted or conditioned by this License or by law, and Licensor promises not to interfere with or be responsible for such uses by You. 16) Modification of This License. This License is Copyright © 2005 Lawrence Rosen. Permission is granted to copy, distribute, or communicate this License without modification. Nothing in this License permits You to modify this License as applied to the Original Work or to Derivative Works. However, You may modify the text of this License and copy, distribute or communicate your modified version (the "Modified License") and apply it to other original works of authorship subject to the following conditions: (i) You may not indicate in any way that your Modified License is the "Academic Free License" or "AFL" and you may not use those names in the name of your Modified License; (ii) You must replace the notice specified in the first paragraph above with the notice "Licensed under <insert your license name here>" or with a notice of your own that is not confusingly similar to the notice in this License; and (iii) You may not claim that your original works are open source software unless your Modified License has been approved by Open Source Initiative (OSI) and You comply with its license review and certification process.
