$periodic<TValue> static method

PeriodicBindableProperty<TValue> $periodic<TValue>({
  1. required Duration duration,
  2. required TValue tickToValue(
    1. int tick
    ),
  3. required TValue initial,
  4. int initialTick = 0,
  5. bool autostart = false,
  6. int? repeat,
  7. void onTick(
    1. int tick
    )?,
  8. void statusChanged(
    1. PeriodicBindableProperty<TValue>
    )?,
  9. PropertyValueChanged<TValue>? valueChanged,
})

创建具有周期性的绑定属性

duration 指定周期间隔时长

tickToValue 指定将 tick 转换为值的方法

initial 指定初始值

initialTick 指定初始 tick 值，默认为 0

autostart 是否自动开始，默认为 false

repeat 指定重复次数，其值为 null 或 0 时为不限次数，默认为 null

onTick 指定每次 tick 的回调方法

statusChanged 指定属性状态变更后的回调方法

valueChanged 指定属性值变更后的回调方法

Implementation

        required TValue Function(int tick) tickToValue,
        required TValue initial,
        int initialTick = 0,
        bool autostart = false,
        int? repeat,
        void Function(int tick)? onTick,
        void Function(PeriodicBindableProperty<TValue>)? statusChanged,
        PropertyValueChanged<TValue>? valueChanged}) =>
    PeriodicBindableProperty(
        duration: duration,
        tickToValue: tickToValue,
        initial: initial,
