felixblaschke/simple_animations

This system is a Flutter animation library that provides declarative widgets and controller extensions for managing complex animation sequences. It enables developers to define, play, loop, and mirror animations using a modular builder API and a modern MovieTween engine. The package also includes a visual debugging overlay to inspect and control animation timelines during development.

6 changes.

The project underwent a significant API restructuring, replacing the legacy InstantAnimation widget with modular builder widgets and controller extensions to simplify animation control. This release aligned the package with Flutter 3.44.0, updating dependencies and removing legacy Android plugin registration mechanisms. Documentation was also enhanced by converting the example app into a structured reference guide with generated code snippets.

This period focused on enhancing the library's animation capabilities by introducing new builder widgets with explicit control and delay support, alongside a new developer tools overlay for debugging. The underlying MovieTween API was restructured for version 5, and the AnimationMixin was updated to respect TickerMode for better performance. Comprehensive test suites were added to verify the behavior of these new features and existing components.

A new \AnimationDeveloperTools\ widget has been added to the library, providing a visual overlay for debugging custom animations. This tool allows developers to play, pause, and scrub through animation timelines, adjust playback speed, and define specific value bounds (lower and upper) for animation ranges. It is designed to be integrated into applications by wrapping existing widgets, with a toolbar that can be positioned at the top or bottom of the screen or hidden entirely.

The \lib/animation\_builder\ package now includes \CustomAnimationBuilder\, \PlayAnimationBuilder\, \LoopAnimationBuilder\, and \MirrorAnimationBuilder\. These widgets wrap the \simple\_animations\ library to provide declarative animation control. \CustomAnimationBuilder\ introduces a \Control\ enum (play, stop, loop, mirror, etc.) and a \delay\ parameter to manage animation timing and state. The specialized builders (\Play\, \Loop\, \Mirror\) expose simplified APIs for common animation patterns while leveraging the underlying control logic.

The AnimationMixin implementation has been updated to integrate with Flutter's TickerMode API. This ensures that animations managed by the mixin are automatically muted or paused when the widget tree is hidden (e.g., in background tabs or off-screen), improving performance and battery life. The change involves wiring the mixin to listen to TickerMode notifications and applying the muted/forceFrames state to all created tickers.

The example app in example/sa\_flutter\_app has been regenerated to align with the default structure of Flutter 3.24. This update introduces several platform-specific changes: on Android, the MainActivity now extends FlutterActivity and the AndroidManifest.xml includes the required \<queries\> block for text processing; on iOS, the AppDelegate now implements FlutterImplicitEngineDelegate to support the implicit engine, and the project uses the modern SceneDelegate pattern. Additionally, the Dart analysis options have been updated to include the recommended flutter\_lints package, and the Gradle wrapper has been upgraded to version 9.1.0.

The example application's main entry point (main.dart) has been removed and replaced by a new, comprehensive documentation file (example.md) that uses the readme\_helper package to generate and embed code snippets. This change shifts the example from a single runnable app to a structured reference guide covering various animation builders, tweens, and mixins, providing users with copy-pasteable code examples for different animation patterns.

The MovieTween library has been updated to Version 5, introducing a new API for defining sequential or parallel animations. The \MovieTween\ class now uses a builder pattern with \scene()\ and \tween()\ methods to define animation properties, replacing the previous constructor-based approach. The library no longer depends on the \package:collection\ package, relying instead on standard Dart and Flutter APIs for sorting and list operations. This change affects how users define and configure multi-property animations, requiring updates to existing code that relied on the old constructor signature.

The library has restructured its public API by removing the legacy \InstantAnimation\ widget and introducing \AnimationControllerExtension\ methods (\play\, \playReverse\, \loop\, \mirror\) for easier animation control. The exports now include a suite of new builder widgets (\CustomAnimationBuilder\, \LoopAnimationBuilder\, \MirrorAnimationBuilder\, \PlayAnimationBuilder\), an \AnimationMixin\, developer tools, and \MovieTween\, replacing the previous single-widget approach with a more modular set of components.

The Android module no longer includes the auto-generated \GeneratedPluginRegistrant.java\ class or the \local.properties\ file containing hardcoded local SDK paths. This indicates a shift away from the older Flutter plugin registration mechanism (likely moving to the new V2 embedding or direct plugin initialization), which simplifies the build configuration by removing machine-specific paths and the manual plugin registration stub.

This release updates the package to align with the latest Flutter baseline, requiring Dart SDK ^3.12.0, Flutter \>=3.44.0, and flutter\_lints ^6.0.0. It fixes a compatibility issue with Flutter's updated TickerMode API in AnimationMixin and adds regression tests to ensure correct behavior. The example app dependencies have been updated to match current Flutter project defaults, and the README has been improved.

(repo-wide) · high confidence

Added tests for AnimationMixin controller modes and TickerMode integration; Added unit tests for MovieTween timeline and property behaviors; Added widget tests for AnimationDeveloperTools; Added widget tests for animation builders and controller extensions; Removed test for InstantAnimation widget.

The example app (sa\_flutter\_app) has been regenerated to use the latest Flutter project structure, including Kotlin DSL build scripts (build.gradle.kts), Android Gradle plugin 9.0.1, and Kotlin 2.3.20, while the main simple\_animations package has been updated to version 5.3.0 with a Dart SDK constraint of ^3.12.0 and Flutter \>=3.44.0. Additionally, the linter dependency flutter\_lints has been upgraded to version 6.0.0 in the main package and 5.0.0 in the example, and the pub.dev URL scheme has been standardized from pub.dartlang.org to pub.dev across lockfiles.
