如何在 flutter 中将有状态小部件转换为无状态小部件？

Question

I have a stateful widget and I want to convert it into a stateless widget. I know how to convert a Stateless widget into a Stateful widget. Just like a Stateless widget is there any shortcut available to convert a Stateful widget.

I am using an Android Studio. Thanks:)

Answer 1

One Simple Trick

    class Counter extends StatelessWidget {
//   @override
//   _CounterState createState() => _CounterState();
// }

// class _CounterState extends State<Counter> {
  @override
  Widget build(BuildContext context) {
    return Container(
      
    );
  }
}

Just comment in between and change the statefulwidget to statelesswidget

Answer 2

No there is no keyboard shortcut until now

Answer 3

You can use @Nirmal 's Trick for converting to stateless and for Renaming variables(gotta convert from widget.variable to just variable) you can just Find widget. and replace with empty value like this and hit replace all

Answer 4

There is no shortcut on Android studio. Best option change 'StatefulWidget' to 'StatelessWidget' and delete the associated boiler plate code.

class TaskTile extends StatefulWidget {
  @override
  _TaskTileState createState() => _TaskTileState();
}

Change to:

 class TaskTile extends StatelessWidget {

    }

Simple three steps on android studio to convert stateful widget to stateless widget

1. comment state class of the stateful widget and delete the commented area.
2. change the stateful widget name that the class extends to statelessWidget
3. press control R, and it will open two text fields for replace function above your code, press widget. into the upper text field, and leave the lower one empty , then click on replace all button . This process will help you convert all the final variables that were convert by the stateful Widget back to what they were before.

Answer 6

Hover your cursor to StatelessWidget and use option + return, IDE will show you to convert this class to a Stateful Widget. Tap that option and following code is generated for you.

Answer 7

In most cases it wouldn't even make sense. Stateless widgets are a subset of stateful widgets. That means that every stateless widget is also a stateful widget.

But not every stateful widget is stateless. So there is a possiblity of breaking code if you would "convert" it.
