Flutter Like Button Animation Not Working After Adding Method

0 votes

I am using the like_button package from this repository (https://pub.dev/packages/like_button) in my Flutter application. The like button animation was working fine under normal conditions. However, after I added a method to be executed when the button is pressed, the animation stopped working as expected.

I can confirm that the method is working properly, but the frontend animation of the like button is not working. It seems to be related to this method, as the animation works fine without it.

Here is the relevant code:

  Future<bool> onLikeButtonTapped(bool isLiked) async {
    print('pressed');

    await toggleFavorite();
    print(success);

    return !isLiked;

    /// if failed, you can do nothing
    // return success? !isLiked:isLiked;
  }
}
Future<void> toggleFavorite() async {
    if (favorites.contains(current)) {
      favorites.remove(current);
    } else {
      favorites.add(current);
    }
    print(favorites);
    notifyListeners();
  }

The toggleFavorite() function, which is an asynchronous function that performs some operation. After adding this method, the like button animation stopped working. But the function is working properly and I can see the output.

It seems like the issue might be related to the fact that the toggleFavorite() method is an asynchronous function. When you use await inside the onLikeButtonTapped method, it might be causing the animation to halt until the toggleFavorite() function is completed.

To fix this, you can try removing the await keyword before toggleFavorite() and instead using then() to handle the result of the function.
