run time error - Could not find io.objectbox:objectbox-android-objectbrowser:<3.5.1>

[DktPhl2019]

I open emulator, run the app, and the error occurs. The error occurs each time I run the app. My Goal: I want to see Android App data saved using ObjectBox Admin on Windows.

The error message:

===========================================================================

      _admin = Admin(store);}
    taskBox = Box<Task>(store);}

  static Future<ObjectBox> create() async {

@DktPhl2019 Replace debugImplementation("io.objectbox:objectbox-android-objectbrowser:<3.5.1>") with debugImplementation("io.objectbox:objectbox-android-objectbrowser:3.5.1"). Note the removal of the diamonds (<>).

I have updated https://docs.objectbox.io/data-browser#setup to make this more clear.

objectbox: ^1.7.2 objectbox_flutter_libs: any

For some reason I have to Setup like this.

dependencies {
     implementation "io.objectbox:objectbox-android:3.5.1"
     debugImplementation("io.objectbox:objectbox-android-objectbrowser:3.5.1")
}

But the docs are not mentioning this additional line.
