1. How do I configure the function of compiling a project with multiple app packages?

please refer to Supporting Multiple Flavors.

2. What are the differences between ID Token-based integration and Authorization Code-based integration?

If you already have one server, choose the Authorization Code mode.

Both modes require user authorization for the first sign-in.

When the authentication information expires, the ID Token mode requires user authentication for each sign-in, just like the first sign-in.

However, for the Authorization Code mode, when the authentication information expires, a new access token can be obtained from the server, which is faster, more reliable, and more convenient.
