Getting "No Directionality widget found" error

[12people]

After wrapping my MaterialApp.router widget with SendbirdUIKit.provider, I get this error:

FlutterError (No Directionality widget found.
_Theater widgets require a Directionality widget ancestor.
The specific widget that could not find a Directionality ancestor was:
_Theater
The ownership chain for the affected widget is: "_Theater ← Overlay ← _FToastHolder ← Builder ← _InheritedProviderScope<SBUMessageCollectionProvider?> ← ChangeNotifierProvider ← _NestedHook ← _InheritedProviderScope<SBUGroupChannelCollectionProvider?> ← ChangeNotifierProvider ← _NestedHook ← ⋯"
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.)
