🌈 Material Design colors
Material Design specifies different opacities of white and black colors to use for text of different emphases on colored backgrounds. You can now use the
disabledOnColor extension getters on
Color to make your text legible!
There are also getters on
ThemeData for contrast colors on the primary, accent, background, and error colors.
Access your navigation-related information via extension methods:
Push a new route and pop all previous routes (e.g., when signing out the user):
navigator.pushAndRemoveAll(/* new route */); // Or using a named route: navigator.pushNamedAndRemoveAll(/* route name */);
Log navigation events to the console:
MaterialApp( navigatorObservers: [LoggingNavigatorObserver()], // ... ) // Prints: // Navigator: didPush /dashboard → /articles/12345 // Navigator: didPop /dashboard ← /articles/12345

A container wrapping multiple buttons with an interpunct (

FlatButtons as children.
Did you ever want to show a subtitle (in addition to a main title) in your
TitleAndSubtitle (very creative name, I know):
AppBar( title: TitleAndSubtitle( title: Text('My title'), subtitle: Text('My optional subtitle'), ), )
