Flutter中的flutter_riverpod如何更方便的将ConsumerWidget转换为ConsumerStatefulWidget？

Question

I am using flutter_riverpod package.

I want to convert ConsumerWidget to ConsumerStatefulWidget .

However, it took me a lot of time to do it like this:

1. (code)

class Widget extends ConsumerWidget {
  const Widget({super.key});
  @override
  Widget build(BuildContext context, WidgetRef ref) {
    return …;
  }
}

2. (remove ref )

class Widget extends ConsumerWidget {
  const Widget({super.key});
  @override
  Widget build(BuildContext context) {
    return …;
  }
}

3. (change ConsumerWidget to StatelessWidget )

class Widget extends StatelessWidget {
  const Widget({super.key});
  @override
  Widget build(BuildContext context) {
    return …;
  }
}

4. (converted by the Convert to StatefulWidget action)

class Widget extends StatefulWidget {
  const Widget({super.key});

  @override
  State<Widget> createState() => _WidgetState();
}

class _WidgetState extends State<Widget> {
  @override
  Widget build(BuildContext context) {
    return …;
  }
}

5. (add Consumer word)

class Widget extends ConsumerStatefulWidget {
  const Widget({super.key});

  @override
  ConsumerState<Widget> createState() => _WidgetState();
}

class _WidgetState extends ConsumerState<Widget> {
  @override
  Widget build(BuildContext context) {
    return …;
  }
}

As you can see, I need to use 5 steps to do it. Is there a faster way?

Feel free to leave a comment if you need more information.

How to convert ConsumerWidget to ConsumerStatefulWidget more easily? I would appreciate any help. Thank you in advance!

Answer 1

If my ConsumerWidget has no parameters,

• 1. Create a new ConsumerStatefulWidget with the same name.
• 2a. Copy content of build method of ConsumerWidget to a new created widget.
• 2b. (If there are other methods in the ConsumerWidget ) Copy content of ConsumerWidget to a new created widget. Then remove ref from build .
• 3. Delete ConsumerWidget .

If my ConsumerWidget has parameters, then I'm doing the same as you, because otherwise I'll have to add a widget. before widget variables.
