simplify adding a single-child parent Widget

From @HansMuller on February 19, 2016 0:13

This comes up all the time as one realizes that a widget needs padding, or a border, or a background, etc.

Say I start with this:

  return new Foo(
    child: new Column(
      justifyContent: FlexJustifyContent.start,
      children: <Widget>[
        ...
      ]
    )
  );

and I want to end up with this:

return new Foo(
  child: new Padding(
    padding: const EdgeDims.all(16.0),
    child: new Column(
      justifyContent: FlexJustifyContent.start,
      children: <Widget>[
        ...
      ]
    )
  )
);

I’d like to be able to put the cursor inside the Column(), press a magic key to get:

return new Foo(
  child: new TBD(
    child: new Column(
      justifyContent: FlexJustifyContent.start,
      children: <Widget>[
        ...
      ]
    )
  )
);

which is easily finished by changing TBD to Padding and add the padding: parameter.

I strongly believe that this functionality should live in DAS and its plugins.

Yes, please!

I heard this feature was shown in a recent demo.

It was and went over great! 👍
