@hugo-sna could you provide a full sample |
|
My main file only contains the widget void main() {
runApp(const MyApp());
}
class MyApp extends StatefulWidget {
const MyApp({super.key});
@override
State<MyApp> createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
@override
Widget build(BuildContext context) {
return ZoomDrawer(
mainScreen: HomePage(),
menuScreen: Menu(),
);
}
}And the full exception |
|
You should have a MaterialApp widget in the root of your app

══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════
The following assertion was thrown building RawGestureDetector(state:
RawGestureDetectorState#03867(gestures: [horizontal drag], behavior: translucent)):
No Directionality widget found.
Stack widgets require a Directionality widget ancestor to resolve the 'alignment' argument.
The default value for 'alignment' is AlignmentDirectional.topStart, which requires a text direction.
The specific widget that could not find a Directionality ancestor was:
Stack
The ownership chain for the affected widget is: "Stack ← Listener ← _GestureSemantics ←
RawGestureDetector ← GestureDetector ← ZoomDrawer ← MyApp ← MediaQuery ← _MediaQueryFromView ←
_ViewScope ← ⋯"
Typically, the Directionality widget is introduced by the MaterialApp or WidgetsApp widget at the
top of your application widget tree. It determines the ambient reading direction and is used, for
example, to determine how to lay out text, how to interpret "start" and "end" values, and to resolve
EdgeInsetsDirectional, AlignmentDirectional, and other *Directional objects.
Instead of providing a Directionality widget, another solution would be passing a non-directional
'alignment', or an explicit 'textDirection', to the Stack.
The relevant error-causing widget was:
GestureDetector
GestureDetector:file:///C:/Users/Nougator/AppData/Local/Pub/Cache/hosted/pub.dev/flutter_zoom_drawer-3.0.1/lib/flutter_zoom_drawer.dart:729:23
