AppButton class

Themed button with elevated, filled, outline, and text styles.

Renders a label with optional leading/trailing icons and resolves enabled, pressed, and disabled states from component colour tokens.

When onPressed returns a Future and showLoadingIndicator is true, the button disables itself and replaces its label with a spinner until the future completes — so callers get built-in async feedback without managing their own loading state.

Properties

enabled → bool
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.

label → String
final
leadingIcon → Widget?
final
onError → FutureOr<void> Function()?
Called if onPressed throws. If null, the error is rethrown once the loading state has been cleared.
final
onPressed → FutureOr<void> Function()?
Called when tapped. May be synchronous or asynchronous; when it returns a Future and showLoadingIndicator is true, the button shows a spinner and is disabled until that future completes. If null, the button is disabled.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
showLoadingIndicator → bool
Whether to show a spinner (and disable the button) while an asynchronous onPressed is running.
