RadioSettingsTile<T> class

RadioSettingsTile is a widget that has a list of Radio widgets with given title, subtitle and default/group value which determines which Radio will be selected initially.

This widget support Any type of values which should be put in the preference. However, since any types of the value is supported, the input for this widget is a Map to the required values with their string representation.

For example if the required value type is a boolean then the values map can be as following: <bool, String> { true: 'Enabled', false: 'Disabled' }

So, if the Enabled value radio is selected then the value true will be stored in the preference

Complete Example:

RadioSettingsTile<int>(
  title: 'Preferred Sync Period',
  settingKey: 'key-radio-sync-period',
  values: <int, String>{
    0: 'Never',
    1: 'Daily',
    7: 'Weekly',
    15: 'Fortnight',
    30: 'Monthly',
  },
  selected: 0,
  onChange: (value) {
    debugPrint('key-radio-sync-period: $value days');
  },
)
