Direzione di ricerca

Start by reproducing the issue with Flutter 3.47 and the standalone material_ui package, then inspect serverpod_auth_idp_flutter's lib/src/common/widgets/text_field.dart, named in the error. Check how SignInWidget provides the Material widget and localization dependencies. Done means SignInWidget renders without the compatibility bridge or the reported exceptions.

Describe the bug

When using Flutter 3.47's new material_ui package structure, SignInWidget from serverpod_auth_idp_flutter no longer renders, with the following error:

══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════
The following assertion was thrown building TextField(controller:
TextEditingController#81f05(TextEditingValue(text: ┤├, selection: TextSelection.invalid, composing:
TextRange(start: -1, end: -1))), enabled: true, decoration: InputDecoration(labelText: "Email",
contentPadding: EdgeInsets(12.0, 14.0, 12.0, 14.0), border: OutlineInputBorder()), keyboardType:
TextInputType(name: TextInputType.emailAddress, signed: null, decimal: null), dirty, dependencies:
[MediaQuery, UnmanagedRestorationScope], state: _TextFieldState#f7467):
No Material widget found.
TextField widgets require a Material widget ancestor within the closest LookupBoundary.
In Material Design, most widgets are conceptually "printed" on a sheet of material. In Flutter's
material library, that material is represented by the Material widget. It is the Material widget
that renders ink splashes, for instance. Because of this, many material library widgets require that
there be a Material widget in the tree above them.
To introduce a Material widget, you can either directly include one, or use a widget that contains
Material itself, such as a Card, Dialog, Drawer, or Scaffold.
The specific widget that could not find a Material ancestor was:
TextField
The ancestors of this widget were:
...
CustomTextField
EmailTextField
Column
Expanded
Column
...

The relevant error-causing widget was:
TextField
TextField:file:///Users/me/.pub-cache/hosted/pub.dev/serverpod_auth_idp_flutter-3.4.13/lib/src/common/widgets/text_field.dart:44:12

You can work around this by importing package:flutter/material.dart instead of package:material_ui/material_ui.dart in the dart file where SignInWidget is used. However you then encounter a futher error:

No MaterialLocalizations found.
TextField widgets require MaterialLocalizations to be provided by a Localizations widget ancestor.

You can work around this by using the temporary MaterialUiCompatibilityBridge workaround documented in material_ui, however this is already deprecated and will be removed at some point in the future:

MaterialApp(
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: const Color(0xFF6750A4)),
      ),
      builder: (BuildContext context, Widget? child) {
        return MaterialUiCompatibilityBridge(child: child!);
      },
      home: const HomeScreen(),
    )
To reproduce
Expected behavior

I would expect to be able to use SignInWidget with the latest version of flutter without resorting to workarounds
