Description
Describe the bug When re-arranging the items with any fluent buttons in ReorderableListView.builder, it throws an assertion on AnimatedDefaultTextStyle
Additional context
ReorderableListView.builder(
shrinkWrap: true,
buildDefaultDragHandles: false,
itemCount: numbers.length,
onReorder: (oldIndex, newIndex) {
setState(() {
if (oldIndex < newIndex) {
newIndex -= 1;
}
final int item = numbers.removeAt(oldIndex);
numbers.insert(newIndex, item);
});
},
itemBuilder: (context, index) {
final number = numbers.elementAt(index);
return ReorderableDragStartListener(
key: ValueKey(index),
index: index,
child: number.isOdd
? ListTile(
key: Key('$index'),
// Fluent button
tileColor: ButtonState.all(Colors.purple),
leading: Button(
onPressed: null,
child: Text(number.toString()),
),
title: Text(number.toString()),
)
: ListTile(
key: Key('$index'),
// Material button
tileColor: ButtonState.all(Colors.blue),
leading: mt.TextButton(
onPressed: null,
child: Text(number.toString()),
),
title: Text(number.toString()),
),
);
},
)
══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════
The following assertion was thrown building AnimatedDefaultTextStyle(duration: 167ms, debugLabel:
((englishLike bodyMedium 2014).merge(whiteRedmond bodyMedium)).merge(unknown), inherit: false,
color: Color(0xffffffff), family: Segoe UI, size: 14.0, weight: 400, baseline: alphabetic,
decoration: TextDecoration.none, textAlign: center, softWrap: wrapping at box width, overflow: clip,
dirty, state: _AnimatedDefaultTextStyleState#c44ab(ticker active)):
Failed to interpolate TextStyles with different inherit values.
The TextStyles being interpolated were:
from: TextStyle(inherit: true, color: Color(0xffffffff), size: 14.0, weight: 400)
to: TextStyle(debugLabel: ((englishLike bodyMedium 2014).merge(whiteRedmond bodyMedium)).merge(unknown), inherit: false, color: Color(0xffffffff), family: Segoe UI, size: 14.0,
weight: 400, baseline: alphabetic, decoration: TextDecoration.none)
The following fields are unspecified in both TextStyles:
"backgroundColor", "letterSpacing", "wordSpacing", "height", "decorationColor",
"decorationThickness".
When "inherit" changes during the transition, these fields may observe abrupt value changes as a
result, causing "jump"s in the transition.
In general, TextStyle.lerp only works well when both TextStyles have the same "inherit" value, and
specify the same fields.
If the TextStyles were directly created by you, consider bringing them to parity to ensure a smooth
transition.
If one of the TextStyles being lerped is significantly more elaborate than the other, and has
"inherited" set to false, it is often because it is merged with another TextStyle before being
lerped. Comparing the "debugLabel"s of the two TextStyles may help identify if that was the case.
For example, you may see this error message when trying to lerp between "ThemeData()" and
"Theme.of(context)". This is because TextStyles from "Theme.of(context)" are merged with TextStyles
from another theme and thus are more elaborate than the TextStyles from "ThemeData()" (which is
reflected in their "debugLabel"s -- TextStyles from "Theme.of(context)" should have labels in the
form of "(<A TextStyle>).merge(<Another TextStyle>)"). It is recommended to only lerp ThemeData with
matching TextStyles.
The relevant error-causing widget was:
