## Summary

The Material widgets `Switch`, `SwitchListTile`, `Checkbox`,
`CheckboxListTile`, `Radio`, `RadioListTile` now use
`ColorScheme.secondary` color for their toggleable widget.
`ThemeData.toggleableActiveColor` is deprecated and will eventually be removed.

## Context

The migration of widgets that depend on `ThemeData.toggleableActiveColor`
to `ColorScheme.secondary` caused  the `toggleableActiveColor` property
to be unnecessary. This property will eventually be removed, as per Flutter's
[deprecation policy](/release/compatibility-policy#deprecation-policy).

## Description of change

The widgets using `ThemeData.toggleableActiveColor` color for the
active/selected state now use `ColorScheme.secondary`.

## Migration guide

Toggleable widgets' active/selected color can generally be customized in 3 ways:

1. Using ThemeData's `ColorScheme.secondary`.
2. Using components themes `SwitchThemeData`, `ListTileThemeData`,
   `CheckboxThemeData`, and `RadioThemeData`.
3. By customizing the widget's color properties.

Code before migration:

```dart
MaterialApp(
  theme: ThemeData(toggleableActiveColor: myColor),
  // ...
);
```

Code after migration:

```dart
final ThemeData theme = ThemeData();
MaterialApp(
  theme: theme.copyWith(
    switchTheme: SwitchThemeData(
      thumbColor: MaterialStateProperty.resolveWith<Color?>(
          (Set<MaterialState> states) {
        if (states.contains(MaterialState.disabled)) {
          return null;
        }
        if (states.contains(MaterialState.selected)) {
          return myColor;
        }
        return null;
      }),
      trackColor: MaterialStateProperty.resolveWith<Color?>(
          (Set<MaterialState> states) {
        if (states.contains(MaterialState.disabled)) {
          return null;
        }
        if (states.contains(MaterialState.selected)) {
          return myColor;
        }
        return null;
      }),
    ),
    radioTheme: RadioThemeData(
      fillColor: MaterialStateProperty.resolveWith<Color?>(
          (Set<MaterialState> states) {
        if (states.contains(MaterialState.disabled)) {
          return null;
        }
        if (states.contains(MaterialState.selected)) {
          return myColor;
        }
        return null;
      }),
    ),
    checkboxTheme: CheckboxThemeData(
      fillColor: MaterialStateProperty.resolveWith<Color?>(
          (Set<MaterialState> states) {
        if (states.contains(MaterialState.disabled)) {
          return null;
        }
        if (states.contains(MaterialState.selected)) {
          return myColor;
        }
        return null;
      }),
    ),
  ),
  //...
)
```
