# Usage

Create an indicator like this:
   ```swift
   ActivityIndicatorView(isVisible: $showLoadingIndicator, type: .default)
   ```
   where  
   `showLoadingIndicator` - bool value you may change to display or hide the indicator  
   `type` - value from `ActivityIndicatorView.IndicatorType` enum

You may alter it with standard SwiftUI means like this: 
   ```swift
   ActivityIndicatorView(isVisible: $showLoadingIndicator, type: .default)
        .frame(width: 50.0, height: 50.0)
        .foregroundColor(.red)
   ```
Or specify another indicator type:

```swift
   ActivityIndicatorView(isVisible: $showLoadingIndicator, type: .growingArc(.red, lineWidth: 4))
       .frame(width: 50.0, height: 50.0)
   ```

### Indicator types
Each indicator type has a number of parameters that have reasonable defaults. You can change them as you see fit, but it is advised to not set them too high or too low.

`default` - iOS UIActivityIndicator style  
```swift
.default(count: 8)
```
`arcs`    
```swift
.arcs(count: 3, lineWidth: 2)
```
`rotatingDots`    
```swift
.rotatingDots(count: 5)
```
`flickeringDots`    
```swift
.flickeringDots(count: 8)
```
`scalingDots`     
```swift
.scalingDots(count: 3, inset: 2)
``` 
`opacityDots`  
```swift
.opacityDots(count: 3, inset: 4)
``` 
`equalizer`  
```swift
.equalizer(count: 5)
```
`growingArc` - add custom color for growing Arc, the default value is `Color.black`      
```swift
.growingArc(.red, lineWidth: 4))
```
`growingCircle` no parameters   
`gradient` - circle with angular gradient border stroke, pass colors ilke this:    
```swift
.gradient([.white, .red], lineWidth: 4)
```
