ButtonState class
This union class represents the state of the button in either a Idling
,
Loading, Success or Error state. This can be considered a enum with extra
utilities for ease of use.
{@tool snippet}
final buttonColor = buttonState.when(
idle: () => Colors.pink,
loading: () => Colors.blue,
success: () => Colors.green,
error: () => Colors.red,
);
{@end-tool}
You can also disregard other states and handle only those you'd like using
the .maybeWhen
syntax.
/// {@tool snippet}
final buttonColor = buttonState.maybeWhen(
idle: () => Colors.pink,
orElse: () => Colors.red,
);
{@end-tool}
