  • Added windows support.
• Added a web-based demo app (URL in the readme file).
• Replaced the deprecated disallowGlow method calls with disallowIndicator.

v1.0.0

• Stable nullsafety release.
• BREAKING: opt into null safety
  • Dart SDK constraints: >=2.12.0-0 <3.0.0
• BREAKING: Removed prevState from IndicatorController class.
  Because flutter only marks the widget that it is ready for rebuild, it is possible that the controller state will change more than once during a single frame what causes one or more steps to be skipped. To still use prevState and didChangeState method, you can use IndicatorStateHelper. Take a look at check_mark_indicator.dart or warp_indicator.dart for example usage.
• Added IndicatorStateHelper class.
• Added IndicatorController unit tests.
• Added warp indicator example.
• Added stopDrag method to the IndicatorController class. It allows you to stop current user drag.

v1.0.0-nullsafety.0

Changes

• opt into null safety
• set Dart SDK constraints to: >=2.12.0-0 <3.0.0
• removed emoji indicator from the example app

v0.9.0

Changes:

• Improved readme documentation.
• Removed material package import.
• Added isComplete and wasComplete controller getters.
• Removed axis property as it can be handled by notificationPredicate.
• Added optional complete indicator state together with completeStateDuration parameter.
• IndicatorControler changes:
  • Added prevoiusState property.
  • Added didStateChange helper method.
  • Added wasArmed, wasDragging, wasLoading, wasHiding and wasIdle properties.
• Added notificationPredicate property to the CustomRefreshIndicator widget.
• Example app:
  • Added initial version of check_mark_indicator. Example that shows how to make use of complete state.

CustomRefreshIndicator widget controller

BREAKING API CHANGES

• Feedback improvements (thank you for your emails!):
  • Changed long identifier names:
    • CustomRefreshIndicatorData => IndicatorController
    • CustomRefreshIndicatorState => IndicatorState
• Update example app

• indicatorBuilder argument is no longer present. Instead use builder argument which has some significant changes.

To animate indicator based on IndicatorControler you can use AnimationBuilder widget and pass IndicatorData object as animation argument. Because of that you can implement your own widget rebuild system what can improve your custom indicator performance (instead of building indicator eg. 300 times you can decide when you want to do it). Example:

return CustomRefreshIndicator(
    child: ListView(children: <Widget>[/* ... */]),
    builder: (
      BuildContext context,
      /// Subtree that contains scrollable widget and was passed
      /// to child argument
      Widget child,
      /// Now all your data will be stored in controller.
      /// To get controller outside of this function
      /// 1. Create controller in parent widget and pass it to CustomRefreshIndicator
      /// 2. Assign [GlobalKey] to CustomRefreshIndicator and access `key.currentState.controller`.
      IndicatorController controller
    ) {
      return AnimatedBuilder(
        // IndicatorData extends ChangeNotifier class so it is possible to
        // assign it to an AnimationBuilder widget and take advantage of subtree rebuild
        animation: controller,
        child: MyPrebuildWidget(),
        child: child,
        builder: (BuildContext context, Widget child) {
          /// TODO: Implement your custom refresh indicator
        },
      );
    },
    onRefresh: myAsyncMethod,
  );
