I am developing a Flutter application and need to launch the Google Wallet app when a user taps a button.

Launch the Google Wallet app directly from my app. Open a specific pass (e.g., a loyalty card, ticket, or payment card) inside Google Wallet. I have tried multiple approaches but have faced various issues. I would like to know the official and reliable method to achieve this on both Android and iOS.

Can you guys please help me with this

Thanks in advance.
