Refreshable widget
Refreshable Widget built for these two Stackoverflow issues, and also for my personal usage. https://stackoverflow.com/q/72025771 https://stackoverflow.com/q/66539533
Possible use case: You have a widget you use with FutureBuilder, shows an async data. But you need to update it periodically because there's no socket or stream that you can listen to. For example a progress for user in a game, which requires you to fetch whole game periodically, like every 20 seconds.
❗ In order to start using Refreshable Widget you must have the Flutter SDK installed on your machine.
Add refreshable_builder to your pubspec.yaml:
dependencies:
refreshable_builder:Install it:
flutter packages get/// pass the type, [num] in below, which is a return type for [refreshCall] and [value] in [builder]
RefreshableWidget<num>(
// optional initial value if you have
initialValue: challenge.userParticipation!.donePercent,
// your API call or logic to refresh
refreshCall: () async {
final challenge = await service.getChallenge(id: widget.challengeId);
return challenge.userParticipation!.donePercent;
},
refreshRate: const Duration(seconds: 20),
// builder, which is called every time you have new value from refreshCall
builder: (context, value) {
return ProgressWidget(
percent: value,
);
},
// optional error and loading widgets
),
