⚡ Bolt: Optimize AppIcon with ThemeExtension #26
Conversation
Refactors `AppIcon` to use a `const` constructor by replacing the mutable `AppIconDefaults` class with an immutable `ThemeExtension` called `AppIconTheme`. This is a significant performance optimization, as it allows Flutter to skip rebuilding `AppIcon` widgets when their parent rebuilds, reducing the overall workload on the UI thread. - Created `lib/theme/app_icon_theme.dart` to define the `AppIconTheme`. - Updated `lib/widgets/app_icon.dart` to remove `AppIconDefaults` and use the new `AppIconTheme` from the theme context. - Integrated `AppIconTheme` into the main app theme in `lib/theme/mono_theme.dart`.

💡 What
Refactored
AppIconto use aconstconstructor by replacing the mutableAppIconDefaultsclass with an immutableThemeExtensioncalledAppIconTheme.🎯 Why
The previous implementation of
AppIconused a mutable, static class for default values, which prevented the use ofconstconstructors. This meant that every instance ofAppIconwas rebuilt whenever its parent widget rebuilt, even if its properties hadn't changed. This causes unnecessary work for the UI thread.📊 Impact
Reduces widget rebuilds significantly on screens with many icons. By using
const AppIcon, Flutter can skip rebuilding these widgets entirely, leading to a smoother user experience and lower CPU usage.🔬 Measurement
This can be verified using the Flutter DevTools Performance view. Before the change, rebuilding a screen with many
AppIconwidgets would show a large number ofAppIconbuilds. After the change, the number ofAppIconbuilds will be dramatically reduced or eliminated for rebuilds that don't change the icons themselves.PR created automatically by Jules for task 9850015487311353154 started by @Doezer
