I have (often) no auto completion in Android Studio when developing a plugin

[rekire]

Steps to reproduce

1. Create a new plugin like this: flutter create --org com.example --template=plugin --platforms=android -a kotlin hello
2. Open the project
3. Edit e.g. android/src/main/kotlin/com/example/hello/HelloPlugin.kt

Actual results

I have code high lighting (but also not always related bug), in that fresh project I cannot jump into the definition of the classes. There is no checking active so I can write code which won't compile without getting the normal linting or error hints.

In my real project I can fix that by opening a new Android Studio Window with the path example/android (in this sample project this even does not work on my computer). However when I open accidentally android directly the io.flutter dependencies cannot be resolved and "everything is red".

The bar "Open for editing in Android Studio" sometimes does not work (nothing happens) or it opens android instead of example/android.

Notes

This is a follow up to discord discussion. Also related is this issue: flutter/flutter#19830

However when I open accidentally android directly the io.flutter dependencies cannot be resolved and "everything is red".

Is this the bug, or is the bug that something Flutter tool is opening android when it shouldn't? Not working unless you open the example is expected behavior due to the way plugins work.

[rekire]

IMHO it should not matter which of those three path (/, /android or /example/android) are opened. Can you share some details why it matters? AFIK you can add modules on the fly in a plugin even if not why not adding code to detect this senario and add a conditional import or dependency to the example module and flutter dependencies.

The ultimate question is why a mixed mode (full dart and Kotlin support) is not possible. If you know a related issue feel free to link it.

Thanks for the report @rekire

I seem to get below upon following the details:

The bar "Open for editing in Android Studio" sometimes does not work (nothing happens) or it opens android instead of example/android.

This seem to worked at my end when it opened and did its thing to sync the gradle changes and open up example:

By this do you mean Gradle Kotlin DSL support ?

[rekire]

With mixed mode I mean that I can edit in the same AS window dart and the Kotlin code with full auto completion and open class defintion, since the IDE has the capabilities to support both languages. Just code highlighting works (almost) every time.

Regarding the second screen on my try I was not able to open the class definition by holding Ctrl (or Command on MacOS) and clicking on the class name or using middle click (of cause just for Windows and MacOS).

Because the Flutter dependency is injected into native projects by flutter build, and flutter build only operates in the context of an application.

why not adding code to detect this senario

I'm not sure what you are proposing adding code to.

why not adding code to detect this senario

I'm not sure what you are proposing adding code to.

If I remember correctly then the flutter dependencies are injected with the plugin 'dev.flutter.flutter-gradle-plugin' which is set in /example/android/app/build.gradle. I would like to add the same plugin to /android/build.gradle which detects the native flutter dependencies and injects the same packages as in the example/app/build.gradle. If this already works (didn't check it yet) why is that not the default?

[darshankawar]

Keeping the issue open for team's tracking.

I updated my IDE now to:

Android Studio Jellyfish | 2023.3.1 Patch 1

That reset all my settings. Then I click for a code file like android/src/main/kotlin/com/example/Example.kt on Open in Android Studio a window pops up and closes directly. (I am aware that I need to open the example app)

Here are the logs:

Is this bug actually a feature request that plugins have syntax highlighting when opened independently of an application or something else?

[rekire]

This is one aspect of the problem. For my workflows it is important that I can edit my dart and flutter code in a single IDE instance. In Android Studio I see sometimes no syntax errors and sometimes everything is red for unresolved dependencies. I cannot work productive that way. My workaround is as pointed out that I open the project from "example/android".

When I use the play button in the Android project mostly the project cannot been build of cause I need to switch the window again. If there would be just one window this would be no issue.

It even become worse when you depend on multiple own packages which you depend on for development as path dependency (via pubspec_overrides.yaml and dependency_overrides:. Then I have to handle often 3 Android Studio instances for a single project: The flutter app which actually used my package, the package (which contains the dart code) and the native Android code.
