Steps to reproduce
- define tabBarTheme with indicator
- use TabBar like
Expected results
documentation in tabs.dart says:
/// If [indicator] is not null or provided from [TabBarTheme],
/// then [indicatorWeight] and [indicatorColor] are ignored.
Actual results
IndicatorWeight is not ignored, 2 pixels are inserted.
Because it is not possible to set value to zero, i used indicatorWeight: 0.0000001 in TabBar as workaround
Code sample
tabBarTheme: Theme.of(context).tabBarTheme.copyWith(
unselectedLabelColor: neutral800,
unselectedLabelStyle: const TextStyle(fontWeight: FontWeight.w600, fontSize: 13),
labelColor: neutral800,
labelStyle: TextStyle(fontWeight: FontWeight.w600, fontSize: 13),
indicatorColor: red500,
dividerColor: Colors.transparent,
indicator: BoxDecoration(
color: neutral100,
borderRadius: BorderRadius.circular(smallBorderRadius),
border: BoxBorder.fromBorderSide(BorderSide(color: neutral800)),
),
indicatorSize: TabBarIndicatorSize.tab,
),
TabBar(
padding: EdgeInsets.symmetric(horizontal: mediumPadding / 2),
indicatorPadding: EdgeInsetsGeometry.symmetric(vertical: mediumPadding / 2),
controller: controller,
tabs: tabs,
onTap: onTap,
),
