Implementation Steps

1

Create Passkey Append Screen

Create a new screen that implements the PasskeyAppendBlock interface. This screen will handle the passkey creation process.
lib/screens/passkey_append.dart
class PasskeyAppendScreen extends HookWidget implements CorbadoScreen<PasskeyAppendBlock> {
  final PasskeyAppendBlock block;
  
  PasskeyAppendScreen(this.block);
2

Add Passkey Creation Button

Implement a button to trigger the passkey creation process.
FilledTextButton(
  isLoading: block.data.primaryLoading,
  onTap: block.appendPasskey,
  content: 'Add Passkey',
),
For a complete implementation example, see the PasskeyAppendScreen implementation on GitHub.
