Automating clicks on another application using Flutter directly is not possible due to Flutter's sandboxed environment and the restrictions on interacting with other apps for security reasons. However, you can achieve this using platform-specific automation tools or libraries like uiautomator in Android.
Here’s a general approach to achieve this:
Identify the button ID: Use uiautomatorviewer or similar tools to find the ID or other identifying attributes of the button you want to click in the target application.
Android Integration: Since uiautomator is specific to Android, you'll need to create a platform channel in Flutter to communicate with native Android code.
Implement Native Code: Write a method in Android (using Java/Kotlin) that uses uiautomator to perform the click action on the identified button.
Flutter-to-Native Communication: Set up method channels in Flutter to call the native method that performs the click action.
