MainApplication.java in React Native 0.61.0

I’m migrating my project from React Native 0.59.9 to 0.61.0 (not advisable, but I have my own reasons). In my existing project I have the following code in MainApplication.java:

@Override
protected List<ReactPackage> getPackages() {
  return Arrays.<ReactPackage>asList(
      new MainReactPackage(),
      RollbarReactNative.getPackage(),
      new VectorIconsPackage(),
      new RNTextInputMaskPackage(),
      new SplashScreenReactPackage(),
      new RNSensitiveInfoPackage(),
      new ReactNativeRestartPackage(),
      new PickerViewPackage(),
      new LinearGradientPackage(),
      new ImagePickerPackage(),
      new RNGestureHandlerPackage(),
      new RNDeviceInfo(),
      new A0Auth0Package(),
      new AsyncStoragePackage()
  );
}

In MainApplication.java in v0.61.0 the following code is auto-generated (corresponds to the code above):

@Override
protected List<ReactPackage> getPackages() {
  @SuppressWarnings("UnnecessaryLocalVariable")
  List<ReactPackage> packages = new PackageList(this).getPackages();
  // Packages that cannot be autolinked yet can be added manually here, for example:
  // packages.add(new MyReactNativePackage());
  return packages;
}

Does it make sense that I would add the packages from the first part of the code to the second like:

@Override
protected List<ReactPackage> getPackages() {
  @SuppressWarnings("UnnecessaryLocalVariable")
  List<ReactPackage> packages = new PackageList(this).getPackages();
  // Packages that cannot be autolinked yet can be added manually here, for example:
  // packages.add(new MyReactNativePackage());
  packages.add(new MainReactPackage())
  packages.add(RollbarReactNative.getPackage())
  packages.add(new VectorIconsPackage())
  packages.add(new RNTextInputMaskPackage())
  packages.add(new SplashScreenReactPackage())
  packages.add(new RNSensitiveInfoPackage())
  packages.add(new ReactNativeRestartPackage())
  packages.add(new PickerViewPackage())
  packages.add(new LinearGradientPackage())
  packages.add(new ImagePickerPackage())
  packages.add(new RNGestureHandlerPackage())
  packages.add(new RNDeviceInfo())
  packages.add(new A0Auth0Package())
  packages.add(new AsyncStoragePackage())
  return packages;
}

Does this make sense?

Answer

You don’t need to add the packages anymore. RN0.60 and above supports auto-linking. I commented out my packages because they are no longer needed.

You will definitely get a similar warning as the image below if you add them.
