There should be a functioning "full" example in the example folder

[Jonas-Sander]

The /example folder should contain an example of using the library with a server framework (shelf, aqueduct).

The perfect case would be:

• Flutter client app which sends a Request with a Token from Firebase-Auth.
• Server which gives a response back to the client.

Challenges:

• How do we combine client and server? Both in a flutter project in different folders?
• Some work is needed here to really get a working example
• Needs Flutter Driver Test

Before that we could at least only do the server and send a known token.
Questions:

• Do we need really run the server locally or does a function callwork?
  • Would be a real running server better to ensure it really works?
• Can we even use a already known token? I dont think so as it will expire.
  • We could use the cloud function endpoint used by the E2E tests to get a valid token.

[Jonas-Sander]

There is now a simple example:

Future<void> main() async {
  final tokenValidator =
      FirebaseAuthTokenValidator(firebaseProjectId: 'my-firebase-project');

  // From e.g. a server request
  final jwt = "your.jwt.here";
  // Throws if JWT is invalid, returns JWT claims if sucessful.
  final claims = await tokenValidator.validateJwt(jwt);
  // Firebase adds the "user_id" claim which is the uid of the FirebaseAuth
  // user.
  final uid = claims['user_id'];
}

would still like to have a example using e.g. shelf so users can see that the token needs to be parsed from the authentication Bearer.
