Flutter 3.47.2 : InputDecoration()

[stephane-couget]

Hello, Great job on this package, it is really useful!

Describe the bug
Upgrading to Flutter 3.47.0+ requires using the material_ui import instead of material.

In the plugin, using InputDecoration for the inputDecoration and searchBoxDecoration properties creates a conflict. We are forced to alias the material import to use InputDecoration, which ultimately triggers an error because the plugin itself relies on dependencies that are too old for the changes required by Flutter.
Package version
I am using version 0.7.5 of intl_phone_number_input.

according to https://flutter.dev/blog/whats-new-in-flutter-3-47, Android Dependency Matrix Header
on code, error editor on InputDecoration is The argument type 'InputDecoration' can't be assigned to the parameter type 'InputDecoration?'

searchBoxDecoration: const flutter_material.InputDecoration(
              labelText: 'Rechercher un pays',
              hintText: 'Nom ou indicatif...',
              prefixIcon: Icon(Icons.search),
              border: flutter_material.OutlineInputBorder(),
            ),
            inputDecoration: flutter_material.InputDecoration(
              labelText: 'Numéro de téléphone',
              border: customBorder,
              // Bordure active lorsque le champ n'a pas le focus mais contient du texte
              enabledBorder: customBorder,
              // Bordure active lorsque le champ a le focus
              focusedBorder: customBorder,
            ),

    final flutter_material.InputBorder customBorder = _hasInput
        ? const flutter_material.OutlineInputBorder(
            borderSide: flutter_material.BorderSide(
              color: Colors.amber,
              width: 2.0,
            ),
          )
        : const flutter_material.OutlineInputBorder(); // Bordure grise standard Flutter quand il n'y a pas de texte

The same thing happens if I remove the import alias to let the material_ui import take over.

Best regards,
