switchThumbFixedSize property
Set to true to keep the Switch thumb size fixed.
When true the Switch thumb size does not change from small size when OFF, to a larger size when ON. This makes the Material-3 Switch even more similar to the iOS style Switch.
This setting only applies to the Material-3 mode, it has no effect in Material-2 mode.
If undefined, defaults to false.
Implementation
final bool? switchThumbFixedSize;
