This is standard Rust behavior, and is unrelated to flutterrustbridge.

Debuggers

Since I have seen some questions asking how logging can be implemented with a Flutter + Rust application, here are some examples.

At Dart side

In this section, we discuss some of the ways to test an application / library

When the Rust code is computationally heavy, you may want to cancel it at the middle when,

Sometimes, we may want to add some logic when things like Dart-call-Rust starts and ends.

By default, during initialization,

Use [frb(init)]

What if our Rust code needs to be stateful?

If you want to use Protobuf, JSON, or whatever serialization methods, it is also quite easy:

This page is only needed to read if you want to use Android NDK in Rust code,

Android/iOS/Linux/MacOS/Windows

Every code change will have to pass the CI with various checks and tons of tests (see the CI part of this page),

When there are some big objects, or even non-encodable objects in the Rust side,

Since it is asked in #1765,

Sometimes, some customization about Rust compilation may be needed,

You can add flutterrustbridge to an existing Cargo Workspace by using the --rust-crate-dir option.
