Answer 1

A different solution will be,

Execute a .bat file from the Java Code

And do all the directory change, and stuff inside the bat file

For instance, my execute.bat file looks like this,

cd flutter_app
flutter build apk
cd ..

And the Java code looks like this,

Process process = Runtime.getRuntime().exec("execute.bat");
