  <p>A simple Flutter widget to declaratively execute initialization logic in your widget tree. Used internally at <a href="https://apps.theodo.com">Theodo Apps</a> ❤️💙💛.</p>
</p>

Flutter widgets often require initialization logic (e.g., fetching data, setting
up listeners) that is typically placed in `initState`, `didChangeDependencies`,
or after the first frame. Managing this logic can lead to boilerplate and less
reusable code, especially when you want to compose or reuse initialization
patterns across widgets.

**init** provides an `Init` widget that lets you declaratively specify
initialization and disposal logic as parameters, making your code cleaner, more
modular, and easier to test.

## Installation

To use the `Init` widget, add `init` package to the dependencies:

```sh
dart pub add init
# or
flutter pub add init
```

You can also add the package manually to your `pubspec.yaml`:

```yaml
dependencies:
  init: ^1.0.0
```

Then run:

```sh
flutter pub get
```

## Usage

Wrap any widget with `Init` and provide the desired callbacks:

```dart
import 'package:init/init.dart';

Init(
  onInit: () => print('Widget initialized'),
  onInitPostFrame: () => print('Widget initialized after frame'),
  onDidChangeDependencies: () => print('Dependencies changed'),
  onDispose: () => print('Widget disposed'),
  child: MyChildWidget(),
)
```

### Parameters

- `onInit`: Called once in `initState` (for one-time setup)
- `onInitPostFrame`: Called once after the first frame is rendered
- `onDidChangeDependencies`: Called in `didChangeDependencies`
- `onDispose`: Called in `dispose`
- `child`: The widget to render

## Example

```dart
Init(
  onInit: () => print('Initializing...'),
  onDispose: () => print('Cleaning up...'),
  child: const Text('Hello!'),
)
```
