Answer 1

You can just replace this code into the
android>>settings.gradle
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
}

Have run into a similar issue and although the suggestion above works (manually changing the gradle rule to look for the .flutter-plugins file) this should be handled by the default android/settings.gradle file.
The root cause for me turned out to be that the plugin's pubspec.yaml didn't have a
flutter:
plugin:
platforms:
android: # <-- was missing
...
entry. This in return caused it not to show up in android plugins of the .flutter-plugins-dependencies file, which in turn made the flutter gradle rules not pick up the dependency
(The .flutter-plugins file is deprecated in favor of .flutter-plugins-dependencies).
