java.lang.ClassCastException when using CardField

[dsling]

Not sure what I'm doing wrong. I created a new stateful class and added the following:

@override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text('Test Stripe'),
        ),
        body: Container(
          alignment: Alignment.center,
          padding: EdgeInsets.all(16),
          child: CardField(
            onCardChanged: (card) {
              print(card);
            },
          ),
        ));
  }
}

However, when I navigate to the screen, I get the following error:

The on-screen keyboard opens up and I see an empty textbox, but I'm unable to type in it. If I replace the CardField with a standard TextField, I get no errors.

Hello, there is an issue in Flutter that affects the keyboard input and we have been forced to implement it like this. The issue is fixed now on master

We will make the needed changes in our package when the next stable version is released
