Unable to get Flutter Add to App working with plugins

I have a Flutter module and I'm trying to add it to my native Android app. I have tried both the AAR approach and the source code approach.

When I try building the AAR, I run the flutter build aar command. I get a long output, but this seems to be the error message:

Plugin project :moor_ffi not found. Please update settings.gradle.
Plugin project :connectivity_macos not found. Please update settings.gradle.
Plugin project :url_launcher_web not found. Please update settings.gradle.

However, this does actually build the debug aar, but not the release.

When I try building my app with the source code, I get this error:

> Configure project :flutter
Plugin project :moor_ffi not found. Please update settings.gradle.
Plugin project :connectivity_macos not found. Please update settings.gradle.
Plugin project :url_launcher_web not found. Please update settings.gradle.

FAILURE: Build failed with an exception.

* Where:
Script '/Users/me/flutter/packages/flutter_tools/gradle/flutter.gradle' line: 738

* What went wrong:
A problem occurred configuring project ':app'.
> Failed to notify project evaluation listener.
   > Could not get unknown property 'android' for project ':app' of type org.gradle.api.Project.
   > Could not get unknown property 'android' for project ':app' of type org.gradle.api.Project.
   > Could not get unknown property 'android' for project ':app' of type org.gradle.api.Project.

I managed to get passed that error message by updating my settings.gradle to this:

def flutterProjectRoot = rootProject.projectDir.parentFile.toPath()

def plugins = new Properties()
def pluginsFile = new File(flutterProjectRoot.toFile(), '.flutter-plugins')
if (pluginsFile.exists()) {
    pluginsFile.withReader('UTF-8') { reader -> plugins.load(reader) }
}

plugins.each { name, path ->
    def pluginDirectory = flutterProjectRoot.resolve(path).resolve('android').toFile()
    include ":$name"
    project(":$name").projectDir = pluginDirectory
}

by reading this issue https://github.com/flutter/flutter/issues/55077. This time I get errors saying that it can't find the Flutter classes. I tried adding the flutter.jar to my project, but that didn't make a difference.

Any help would be appreciated. I've been working on this all day and am about out of ideas.

Here is my flutter doctor output:

UPDATE

The only way I managed to get this to work was to downgrade to an older version of Flutter. I was able to get it working on the beta channel, v1.14.6. This definitely doesn't fix anything, but at least I could make a release build.

Replace all the file app -> android -> settings.gradle with this :

    include ':app'

    def flutterProjectRoot = rootProject.projectDir.parentFile.toPath()

    def plugins = new Properties()
    def pluginsFile = new File(flutterProjectRoot.toFile(), '.flutter-plugins')
    if (pluginsFile.exists()) {
    pluginsFile.withReader('UTF-8') { reader -> plugins.load(reader) }
    }

    plugins.each { name, path ->
    def pluginDirectory = 
    flutterProjectRoot.resolve(path).resolve('android').toFile()
    include ":$name"
    project(":$name").projectDir = pluginDirectory
    }

Please try adding this to your flutter app -> android -> settings.gradle

def flutterProjectRoot = rootProject.projectDir.parentFile.toPath()

def plugins = new Properties()
def pluginsFile = new File(flutterProjectRoot.toFile(), '.flutter-plugins')
if (pluginsFile.exists()) {
    pluginsFile.withReader('UTF-8') { reader -> plugins.load(reader) }
}

plugins.each { name, path ->
    def pluginDirectory = flutterProjectRoot.resolve(path).resolve('android').toFile()
    include ":$name"
    project(":$name").projectDir = pluginDirectory
}

To know more check this.
