🛠 A package absorbing all Flutter utility functions, including extension functions and commonly used widgets.

BuildContext

In Flutter you often see the pattern <Class>.of(context) (e.g. [Theme.of(context)][Theme.of]). This package adds extension getters on [BuildContext][BuildContext] for those classes so you can just say:

context.theme         // ≙ Theme.of(context)
context.textTheme     // ≙ Theme.of(context).textTheme
context.navigator     // ≙ Navigator.of(context)
context.rootNavigator // ≙ Navigator.of(this, rootNavigator: true)
context.scaffold      // ≙ Scaffold.of(context)
context.form          // ≙ Form.of(context)
// ... and many others!

Buttons

Did you ever want to show a progress indicator inside a button? Or were annoyed to conditionally set a Button's onPressed to disable it? Fear no more — black_hole_flutter has got you covered!

In FancyFab (a FloatingActionButton), FancyFlatButton, FancyOutlineButton & FancyRaisedButton, we introduce some new parameters:

• isLoading: Setting this to true shows a CircularProgressIndicator and disables this button. You can optionally specify a loadingChild (loadingLabel on FancyFab) to show next to the progress indicator.
• isEnabled: Settings this to false disables this button, even if onPressed is set.

Material 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 highEmphasisOnColor, mediumEmphasisOnColor and 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.
