FButton class

A button.

FButton typically contains icons and/or a label. If the onPress and onLongPress callbacks are null, then this button will be disabled, and it will not react to touch.

The constants in FBaseButtonStyle provide a convenient way to style a button.

Constructors

FButton.new({required VoidCallback? onPress, required Widget child, FBaseButtonStyle style = Variant.primary, VoidCallback? onLongPress, bool autofocus = false, FocusNode? focusNode, ValueChanged<bool>? onFocusChange, ValueChanged<bool>? onHoverChange, ValueChanged<Set<WidgetState>>? onStateChange, bool selected = false, Widget? prefix, Widget? suffix, bool intrinsicWidth = false, Key? key})
Creates a FButton that contains a prefix, child, and suffix.
FButton.icon({required VoidCallback? onPress, required Widget child, FBaseButtonStyle style = Variant.outline, VoidCallback? onLongPress, bool autofocus = false, FocusNode? focusNode, ValueChanged<bool>? onFocusChange, ValueChanged<bool>? onHoverChange, ValueChanged<Set<WidgetState>>? onStateChange, bool selected = false, Key? key})
Creates a FButton that contains only an icon.
FButton.raw({required VoidCallback? onPress, required Widget child, FBaseButtonStyle style = Variant.primary, VoidCallback? onLongPress, bool autofocus = false, FocusNode? focusNode, ValueChanged<bool>? onFocusChange, ValueChanged<bool>? onHoverChange, ValueChanged<Set<WidgetState>>? onStateChange, bool selected = false, Key? key})
Creates a FButton with custom content.
