custom_refresh_indicator 2.0.0-dev.8

Flutter Widget that make it easy to implement custom refresh indicator.

2.0.0-dev.8

Breaking changes

• Added autoRebuild flag which is by default set to true. From now on, there is no need to wrap widgets in the builder function with the AnimatedBuilder widget, as it will be automatically rebuilt. For optimization purposes, you can use the old behavior by setting the autoRebuild argument to false.
• Remove IndicatorState.hiding state. Instead introduced IndicatorState.finalizing and IndicatorState.canceling.
• Splited IndicatorState.loading state into two phases: IndicatorState.settling and IndicatorState.loading.
• Renamed extentPercentageToArmed argument to containerExtentPercentageToArmed which better describes what it exactly does.
• Changed the default value of the defaultContainerExtentPercentageToArmed from 0.20 to 0.1(6) to match the behavior of the built-in indicator widget.
• Removed deprecated IndicatorStateHelper class. Instead use CustomRefreshIndicator.onStateChanged method.
• Removed deprecated leadingGlowVisible and trailingGlowVisible arguments. Instead use leadingScrollIndicatorVisible and trailingScrollIndicatorVisible accoringly.
• Allow setting the edge of the list that will trigger the pull to refresh action.
  • Introduced IndicatorEdge, IndicatorTrigger, IndicatorSide and IndicatorTriggerMode classes.
  • Replaced reversed argument of the CustomRefreshIndicator class with trigger.
  • Added edge and side properties to the IndicatorController class.
• Added extension with utility getters for IndicatorState class.
• Trigger mode support added. Equivalent to trigger mode of the built-in RefreshIndicator widget.
• The PositionedIndicatorContainer class is no longer exported from this package, however the source code is available in the example application.
• Now the onRefresh function will be triggered immediately when the indicator is released in the armed state. Previously, the onRefresh function was triggered when the indicator reached a target value in the loading state of 1.0.
• Fixed a bug causing the onRefresh method not to be triggered on the iOS platform due to bounce physics.
• Implemented equality operator for IndicatorStateChange class.
• Improved code coverage with tests
• Multiple minor fixes, improvements and optimizations.

1.2.1

• Flutter 3.0.0 migration backward compatibility fix (#31) by Jordan1122

1.2.0

Improvements:

• Compatibility improvements for Flutter 3.0.

1.1.2

Fixes:

• Fixed assertion issue reported and resolved by ziqq in #29. For more information, please take a look at the following issue #28

1.1.1

Fixes:

• Pub.dev readme file fix.
• Fix code formatting issues

1.1.0

Fixes:

• Handle errors thrown from the onRefresh method.

Improvements:

• Updated example app
  • Added support for the Android embedding v2
  • Added web support
  • Added windows support.
• Added a web based demo app (url in the readme file).
• Replaced the deprecated disallowGlow method calls with disallowIndicator.
• Added onStateChanged function argument that allows tracking indicator state changes.
• The IndicatorStateHelper class is now deprecated in favor of onStateChange function and IndicatorStateChange class.
• Initial support for programmatically-controlled indicators has been added. Added the show, hide and refresh methods to the CustomRefreshIndicatorState class. It can be accessed via GlobalKey. Take a look at an programmatically-controlled screen example.
• Use the flutter_lints package for analysis.
• Deprecate leadingGlowVisible and trailingGlowVisible in favor of leadingScrollIndicatorVisible and trailingScrollIndicatorVisible arguments.
• Added reversed argument that allows you to trigger a refresh indicator from the end of the list.
• Added envelope example.
• Added pull to fetch more example.

1.0.0

• 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.

0.9.0

• Improved readme documentation.
• Removed material package import.

0.9.0-dev.2

• Added isComplete and wasComplete controller getters.
• Removed axis property as it can be handled by notificationPredicate.

0.9.0-dev.1

• 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.

0.8.0+1

BREAKING API CHANGES

• Changed long identifier names:
  • CustomRefreshIndicatorData => IndicatorController
  • CustomRefreshIndicatorState => IndicatorState
• 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 you can either:
      /// - Create controller in parent widget and pass it to CustomRefreshIndicator widget
      /// - 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,
  );
