      Description

      I'm trying to set Flat style for my QtQuick.Controls v1 components. Here how I do that in main.cpp:

      #include <QGuiApplication>
      #include <QQmlApplicationEngine>
      
      int main(int argc, char *argv[])
      {
          qputenv("QT_QUICK_CONTROLS_1_STYLE", "Flat");
          qputenv("QT_LABS_CONTROLS_STYLE", "Flat");
      
          QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
          QGuiApplication app(argc, argv);
      
          QQmlApplicationEngine engine;
          const QUrl url(QStringLiteral("qrc:/main.qml"));
          QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
                           &app, [url](QObject *obj, const QUrl &objUrl) {
              if (!obj && url == objUrl)
                  QCoreApplication::exit(-1);
          }, Qt::QueuedConnection);
          engine.load(url);
      
          return app.exec();
      }
      

      It does work on Desktop (macOS) as expected, but it doesn't work on Android. "Base" and "Desktop" styles also work as expected on both Desktop and Android platforms. I put an example project below alongside with the full debug output of it. I can't see any unusual error messages in the debug output though
