[codepgq]

SDK Affected

AppKit

Describe the bug

On the simulator, calling the openModalView() method sometimes catches an unhandled exception

To Reproduce

Steps to reproduce the behavior:

1. init

Future<void> init(
    BuildContext context, {
    required String projectId,
    PairingMetadata? metadata,
  }) async {
    if (_appKit != null) return;
    final appKit = await ReownAppKit.createInstance(
      projectId: projectId,
      metadata: metadata ?? defaultMetadata,
    );

    _appKit = appKit;

    if (context.mounted) {
      _appKitModal = ReownAppKitModal(
        context: context,
        appKit: appKit,
      );

      await _appKitModal?.init();

      _listenSession();
      _listenModal();
      _listenRelayClient();
      debugPrint('default wallet connect init');
    } else {
      throw Exception('Context is not mounted');
    }
  }

2. calling the openModalView()

  @override
  Future<void> connect() async {
    // With no options will open default screen depending on the connection status
    _appKitModal?.openModalView();
  }

3. Sometimes connect failed and show errors

Can you share a complete reproducible code? I have the feeling you are recreating AppKit instance more times than needed.
