fillColor property

MaterialStateProperty<Color?>? fillColor

The color that fills the checkbox, in all WidgetStates.

Resolves in the following states:

• WidgetState.selected.
• WidgetState.hovered.
• WidgetState.focused.
• WidgetState.disabled.

{@tool snippet} This example resolves the fillColor based on the current WidgetState of the Checkbox, providing a different Color when it is WidgetState.disabled.

Checkbox(
  value: true,
  onChanged: (_){},
  fillColor: WidgetStateProperty.resolveWith<Color>((Set<WidgetState> states) {
    if (states.contains(WidgetState.disabled)) {
      return Colors.orange.withOpacity(.32);
    }
    return Colors.orange;
  })
)

{@end-tool}

如果指定，则覆盖 TxRadio.fillColor 的默认值。

Implementation

final MaterialStateProperty<Color?>? fillColor;
