TabBar indicatorPadding doesn't work with hot-reload unless you also change indicatorSize #108102
Description
Steps to Reproduce
- Create a new sample app with
flutter new tabbar-bug. - Edit the
_MyHomePageState.buildmethod so that it looks like the code below. - Start debugging in VS Code. I'm using a physical Pixel 5, rather than the emulator.
- Edit the indicatorPadding value. Note that it doesn't do anything.
- Edit the indicatorSize value. Note that now the indicatorPadding change takes effect (as well as the indicatorSize change).
Expected results:
Editing the indicatorPadding value and hot-reloading should take effect immediately.
Actual results:
You have to hot-restart the app, or also edit indicatorSize, for indicatorPadding to do anything.
Code sample
@override
Widget build(BuildContext context) {
return DefaultTabController(
length: 3,
child: Scaffold(
appBar: AppBar(
title: Text(widget.title),
bottom: TabBar(
indicatorColor: Colors.blue[100],
indicatorSize: TabBarIndicatorSize.label,
indicatorPadding: const EdgeInsets.all(12), // <-- Changes here don't work on hot-reload.
tabs: const [
Tab(text: 'Dogs'),
Tab(text: 'Cats'),
Tab(text: 'Fish')
],
),
),
body: Center(
