thumbIcon property
final
The icon to use on the thumb of this switch
Resolved in the following states:
This example resolves the thumbIcon based on the current
MaterialState of the Switch, providing a different
link
Icon
when it is
MaterialState.disabled.
Switch(
value: true,
onChanged: (bool value) { },
thumbIcon: MaterialStateProperty.resolveWith<Icon?>((Set<MaterialState> states) {
if (states.contains(MaterialState.disabled)) {
return const Icon(Icons.close);
}
return null; // All other states will use the default thumbIcon.
}),
)
If null, then the value of SwitchThemeData.thumbIcon is used. If this is also null, then the Switch does not have any icons on the thumb.
Implementation
final MaterialStateProperty<Icon?>? thumbIcon;
