  • Do I have to consider Flutter App as any other web app like React or HTML? To consider the code can be viewed by users?
    However! A determined user can still do something like load the app on a phone in an Android or iOS simulator, then watch all outgoing API calls and basically reverse-engineer how things work. This is how Teller wrote their system -- they loaded up bank apps onto a simulator and basically reverse-engineered the API for the various banks. Source: over 2 years ago

  • Why do some traditional banks still not offer open banking?
    I had a subscription with TrueLayer. The API service was smooth and their team updated me from time to time. They even helped me with regulation by giving us an agency under their FCA license. Eventually I transferred to Nordigen due to a friend’s recommendation. It was also free so why not. It was easy to integrate their program to my business model.
