The current SDK language version does not match your analyzer package language version

[Larpoux]

Describe the bug

When I execute :

flutter_rust_bridge_codegen generate

instead of

cargo run --manifest-path ../flutter_rust_bridge/frb_codegen/Cargo.toml -- generate

I have many problems.
My FRB generator is : flutter_rust_bridge_codegen 2.1.0.
One of the problems that I get is :

[INFO] Precompiling build script......
[INFO] Precompiling build script... completed, took 5.2s

[WARNING] Attempting to enable experiments `[class-modifiers]`, but the current SDK
language version does not match your `analyzer` package language version:

Analyzer language version: 3.4.0
SDK language version: 3.5.0

In order to use experiments you may need to upgrade or downgrade your
`analyzer` package dependency such that its language version matches that of
your current SDK, see https://github.com/dart-lang/build/issues/2685.

Note that you may or may not have a direct dependency on the `analyzer`
package in your `pubspec.yaml`, so you may have to add that. You can see your
current version by running `pub deps`.

[fzyzcjy]

Hmm, this looks like a general flutter build_runner related question. Firstly, maybe try to use flutter stable version (instead of master version)

[Larpoux]

I switched to the Stable Flutter Channel but it is not very much better.
I confirm that :

cargo run --manifest-path ../flutter_rust_bridge/frb_codegen/Cargo.toml -- generate

works more or less correctely, but :

flutter_rust_bridge_codegen generate

gives me various errors.
Another error that I get is :

What is weird is that I can have many different errors when using flutter_rust_bridge_codegen generate.
cargo run --manifest-path ../flutter_rust_bridge/frb_codegen/Cargo.toml -- generate works better for me.

[fzyzcjy]

Try

flutter_rust_bridge_codegen --version

Are you using the latest version?

And, is it possible you are using some feature that has not been released?

[Larpoux]

My FRB generator is : flutter_rust_bridge_codegen 2.1.0.

[fzyzcjy]

Ok, looks like #2190 is merged but not yet released. I will release 2.2.0 probably within a day (after CI of #2228 is green)

[Larpoux]

No need to hurry. I have many other things to work on ...
Take your time

[fzyzcjy]

2.2.0 has been released before and this should be solved :)
