IOS app crash when initialising wallet

[anton-yatsenko]

I encountered unexpected app crashes on IOS only (android works fine).
Error message: Could not cast value of type 'NSNull' to 'NSString'. Then app crashes.
Caused when calling init method. Issue arises only when redirect field of appMetadata is null, while if I assign redirect an empty string, it works fine.
Code samples: final AppMetadata walletMetadata = AppMetadata( name:name, url: url, description: description, icons: <String>[ icon, ], redirect: "", );
await _walletConnect.init(projectId: 'yourid', appMetadata: walletMetadata);
