Add enableRenderCache parameter (#317)

- Fixed varying opacity stops across keyframes in the same gradient
- Fixed rounded corners for non-closed curves
- Allow to load Telegram Stickers (.tgs)

```dart
Lottie.asset(
  'sticker.tgs',
  decoder: LottieComposition.decodeGZip,
)
```

- Expose a hook to customize how to decode zip archives. This is useful
for dotlottie (.lottie) archives when we want
to specify a specific .json file inside the archive

```dart
Lottie.asset(
  'animation.lottie',
  decoder: customDecoder,
);

Future<LottieComposition?> customDecoder(List<int> bytes) {
  return LottieComposition.decodeZip(bytes, filePicker: (files) {
    return files.firstWhere((f) => f.name == 'animations/cat.json');
  });
}
```

- Remove name property from `LottieComposition`
- `imageProviderFactory` is not used in .zip file by default anymore.
To restore the old behaviour, use:
```dart
Future<LottieComposition?> decoder(List<int> bytes) {
  return LottieComposition.decodeZip(bytes, imageProviderFactory: imageProviderFactory);
}

Lottie.asset('anim.json', imageProviderFactory: imageProviderFactory, decoder: decoder)

+- Add `enableRenderCache` parameter.
+
+```dart
+Lottie.asset('assets/complex_animation.json',
+  enableRenderCache: true,
+)
+```
+
+It allows to opt into a mode where the frames of the animation are rendered lazily in an offscreen cache.
+Subsequent runs of the animation will be very cheap to render.
+
+This is useful is the animation is complex and can consume a lot of energy from the battery.
+It's a trade-off to lower the CPU usage at the cost of an increased memory usage.
+
+The render cache is managed internally and will release the memory once the animation is disposed. 
+The cache is shared between all animations. If 2 `Lottie` widget are rendered at the same size, they will render only 
+once.
+
+Any change in the configuration of the animation (delegates, frame rate etc...) will clear the cache.
+Any change in the size will invalidate the cache. The cache use the final size visible on the screen (with all 
+transforms applied).

+- Disable gradient cache optimization when `ValueDelegate.gradientColor` is used
+- Use `DefaultAssetBundle.of` in `AssetLottie` before fallback to `rootBundle`
+- Add `BuildContext` optional parameter in `LottieProvider.load`
+- Fixed varying opacity stops across keyframes in the same gradient
+- Fixed rounded corners for non-closed curves
+
+## 2.7.0

+- Fix a bug in Text with strokes
+- Fix gradient interpolation for opacity stops beyond the last color stop
+- Add color value callback to solid layer
+
+## 2.6.0

+## 2.5.0
+- Add layer-level opacity option to LottieOptions
+- Fix TextLayer opacity calculation
+
+## 2.4.0
+- Require minimum Dart 3.0.0 and Flutter 3.10.0

+
+## 2.3.1
+- Fix an assertion for null `ShapeTrimPathType.type`.
+
+## 2.3.0
+- Fixed a failed assertion (`dirty: is not true`) when calling `setState` inside `onLoaded` callback.
+- Update point text y offset
+- Makes static compositions not animate by default
+
+## 2.2.0
+Apply the latest fixes from Lottie-Android:
+
+- Overhaul text layout
+- Fix rounded corners modifying already rounded corners
+- Support box position in Document Data
+- Allow interpolating between gradients with different opacity stops
+- Add support for gradient opacity stops
+
+## 2.1.0
+- Improve the cache to ensure that there is not an empty frame each time we load an animation.  
+  The method `AssetLottie('anim.json').load()` returns a `SynchronousFuture` if it has been loaded previously.
+- Expose the `LottieCache` singleton.
+  It allows to change the cache behaviour and clear the entries.
+
+```dart
+void main() {
+  Lottie.cache.maximumSize = 10;
+  Lottie.cache.clear();
+  Lottie.cache.evict(NetworkLottie('https://lottie.com/anim.json'));
+}
+```
+
+## 2.0.0
+- **Breaking change**: the lottie widget will be smaller if it relies on the intrinsic size of the composition. 
+
+Previously the lottie parser was automatically multiplying the size of the composition by `window.devicePixelRatio`.
+This was incorrect as it results in a widget of a different size depending on the pixel ratio of the monitor. 
+Furthermore, it created some bugs when the property `window.devicePixelRatio` was not available immediately at the start
+of the app (on Android release builds). 
+
+The code can be adapted to specify explicitly the size of the animation with `width`, `height` and `fit` properties.
+
+```dart
+Scaffold(
+  body: Center(
+    child: Lottie.asset(
+      'assets/LottieLogo1.json',
+      height: 800,
+      fit: BoxFit.contain,
+    ),
+  ),
+);
+```
+
+## 1.4.3
+- Fixed some lints with Flutter 3.3. 
+
+## 1.4.2
+- Use `FilterQuality.low` as default to draw image layers.
+
+## 1.4.1
+- Allow `AlignmentGeometry` for `alignment`.
+
+## 1.4.0
+- Added `filterQuality` property to control the performance vs quality trade-off to use when drawing images
+
+## 1.3.0
+- Added support for rounded corners on shapes and rects
+- Add support for text in dynamic properties (`ValueDelegate`)
+
+Example:
+
+```dart
+Lottie.asset(
+  'assets/DynamicText.json',
+  delegates: LottieDelegates(values: [
+    ValueDelegate.text(
+      ['Text layer'], // The path to the text element to change
+      value: 'The new text',
+    ),
+  ]),
+)
+```
+
+- Improve stroke with offset
+- Add support for reversed polystar paths
+- Enforce order of operations to avoid rounding errors
+
+## 1.2.2
+- Internal maintenance: fix lints for Flutter 2.10
+
+## 1.2.1
+- Fix: Revert Cubic to `PathInterpolator.cubic`
+
+## 1.2.0
+- Add support for gaussian blurs.
+
+Example to blur some elements dynamically:
+  
+```dart
+Lottie.asset(
+  'assets/AndroidWave.json',
+  delegates: LottieDelegates(values: [
+    ValueDelegate.blurRadius(
+      ['**'], // The path to the element to blur
+      value: 20,
+    ),
+  ]),
+)
+```
+
+- Add support for drop shadows.
+
+Example to add a shadow dynamically:
+```dart
+Lottie.asset(
+  'assets/animation.json',
+  delegates: LottieDelegates(values: [
+    ValueDelegate.dropShadow(
+      ['**'], // The path to the elements with shadow
+      value: const DropShadow(
+        color: Colors.blue,
+        direction: 140,
+        distance: 60,
+        radius: 10,
+      ),
+    ),
+  ]),
+)
+```
+
+## 1.1.0
+- Add `errorBuilder` callback to provide an alternative widget in case an error occurs during loading.
+```dart
+Lottie.network(
+  'https://example.does.not.exist/lottie.json',
+  errorBuilder: (context, exception, stackTrace) {
+    return const Text('😢');
+  },
+);
+```
+
+- Add `onWarning` to be notified when a warning occurs during the animation parsing or painting.
+  Previously the warnings where written in an internal `logger`.
+  ```dart
+  Lottie.asset('animation.json'
+    onWarning: (warning) {
+      _logger.info(warning);
+    },
+  );
+  ```
+- Various bug fixes
+
+## 1.0.1
+- Implement `RenderBox.computeDryLayout`
+
+## 1.0.0
+- Migrate to null safety
+- Fix some rendering bugs
+- Add an image delegate to dynamically change images
+- Allow to use an imageProviderFactory with a zip file
+
+## 0.7.1
+- Fix a crash for some lottie file with empty paths.
+
+## 0.7.0+1
+- Fix Flutter Web compilation error
+
+## 0.7.0
+- Performance improvement for complex animations.
+
+## 0.6.0
+- Runs the animation at the frame rate specified in the json file (ie. An animation encoded with a 20 FPS will only
+  be paint 20 times per seconds even though the AnimationController will invalidate the widget 60 times per seconds).  
+  A new property `frameRate` allows to opt-out this behavior and have the widget to repaint at the device frame rate 
+   (`FrameRate.max`).
+- Automatically add a `RepaintBoundary` around the widget. Since `Lottie` animations are generally complex to paint, a
+   `RepaintBoundary` will separate the animation with the rest of the app and improve performance. A new property `addRepaintBoundary`
+   allows to opt-out this behavior.
+- Fix a bug where we would call `markNeedPaint` when the animation was not changing. This removes unnecessary paints in
+  animations with static periods.
+
+## 0.5.1
+- Remove direct dependencies on dart:io to support Flutter Web
+
+## 0.5.0
+- Support loading animation from network in a web app

-This is a new library so usability, documentation and performance are still work in progress.
+### Frame rate
+By default, the animation is played at the frame rate exported by AfterEffect.
+This is the most power-friendly as generally the animation is exported at 10 or 30 FPS compared to the phone's 60 or 120 FPS.
+If the result is not good, you can change the frame rate
