试图处理 firebase 存储异常不起作用（颤振）

Question

After creating the reference to my file on firebase storage I'm getting it's download URL. Since the file(image) may or may not exist I'm using then and catch error . However it still throws exception. Even the try and catch block doesn't work.

    StorageReference dpRef = FirebaseStorage.instance.ref().child(
          'dp/' + widget.userId,
        );
    dpRef.getDownloadURL().then(
      (value) {
        setState(
          () {
            _dpImgURL = value;
          },
        );
      },
    ).catchError((e) {
      print(e.toString());
    });

What am I doing wrong? New to flutter, so please be gentle.

Answer 1

try catch is not working for firebase storage, no idea why, i fixed like this:

}, onError: (e) {
      debugPrint('Exception::: ==========>>>>>>> ${e.toString()}');
      status(null);
    });

it gets the exception vey well
