Flutter build apk with --enable-software-rendering

问题:

Is it possible to do something like this:

flutter build apk --enable-software-rendering

I need a release version that performs the say way as:

flutter run --enable-software-rendering --profile

Thank you.

TL;DR Put getIntent().putExtra("enable-software-rendering", true); on top of your onCreate()

Note - I assumed Android from the "apk" in question title and the need for software rendering.

Looking at the source code, the --enable-software-rendering flag for flutter run causes the activity to be launched using am start with --ez enable-software-rendering true, which puts that as a boolean extra into the intent.

If you wish to control when to use software rendering from code (such as depending on API level or device model), set the mentioned intent extra early in your onCreate().

Full Example:

import android.os.Bundle;
import io.flutter.facade.Flutter;
import io.flutter.app.FlutterActivity;

public class MyActivity extends FlutterActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {

        // use software rendering (ideally only when you need to)
        getIntent().putExtra("enable-software-rendering", true);

        // start Flutter
        Flutter.startInitialization(this);
        super.onCreate(savedInstanceState);
    }
}
