I think it will resolved by this PR #39

[paraflu]

Waiting for release 💕

[labaxter]

I decided I did not want to wait any longer for a new release. I can confirm that changing compileSdkVerion in android/build.gradle from

compileSdkVersion 28

to

compileSdkVersion 31

fixes the problem.

Steps I used to verify this:

1. git clone external_app_launcher (via git URL)
2. change android/compileSdkVerion to 31 (from 28)
3. changed my reference to external_app_launcher to cloned project via path: in my pubspec.yaml.
4. ran pub get in my project
5. Tested my application. It compiled and functioned correctly.

The PR #39 should be merged, and a new release produced.

In the meantime, I'll be running off my fixed clone.

For a "fix" to other packages with the same problem, see also flutter/flutter#153281 (comment)

TLDR; in your flutter project, in android\build.gradle, add this code before the other subprojects sections:

subprojects {
    afterEvaluate { project ->
        if (project.extensions.findByName("android") != null) {
            Integer pluginCompileSdk = project.android.compileSdk
            if (pluginCompileSdk != null && pluginCompileSdk < 31) {
              project.logger.error(
                "Warning: Overriding compileSdk version in Flutter plugin: "
                  + project.name
                  + " from "
                  + pluginCompileSdk
                  + " to 31 (to work around https://issuetracker.google.com/issues/199180389)."
                  + "\nIf there is not a new version of " + project.name + ", consider filing an issue against "
                  + project.name
                  + " to increase their compileSdk to the latest (otherwise try updating to the latest version)."
                )
                project.android {
                    compileSdk 31
                }
            }
        }
    }
}
