TimerControllerBuilder class

TimerControllerBuilder handles building a widget in response to new value. Please refer to TimerControllerListener if you want to "do" anything in response to value changes such as navigation, showing a dialog, etc...

TimerControllerBuilder(
  controller: myTimerController,
  builder: (context, value, child) {
  // return widget here based on myTimerController
  }
)

An optional buildWhen can be implemented for more granular control over how often TimerControllerBuilder rebuilds. buildWhen will be invoked on each controller value change. buildWhen takes the previous and current value and must return a bool which determines whether or not the builder function will be invoked. The previous value will be initialized to the value of the controller when the TimerControllerBuilder is initialized. buildWhen is optional and if omitted, it will default to true.

TimerControllerBuilder(
  controller: myTimerController,
  buildWhen: (previous, current) {
    // return true/false to determine whether or not
    // to rebuild the widget with state
  },
  builder: (context, value, child) {
    // return widget here based on myTimerController value
  }
)

Properties

builder → TimerControllerWidgetBuilder
The builder function which will be invoked on each widget build. The builder takes the BuildContext the current value and a child and must return a widget.
