TfChoiceSetting<T extends Object> class

单选设置项：从 options 中选一个值保存。

选项不超过 inlineLimit 个时直接显示为分段选择器；更多时显示当前值， 点击后弹出对话框选择。偏好值是枚举时，用 TfChoiceSetting.enumeration。

const TfChoiceSetting<int>(
  key: AppKeys.syncInterval,
  title: '同步间隔',
  options: [TfChoice(15, '15 分钟'), TfChoice(60, '1 小时'), TfChoice(1440, '每天')],
)
