How to wrap real html child after remove buildAsyncBuilder

[ykrank]

Use case

Before, i use buildAsyncBuilder to get real html height, like:

buildAsyncBuilder: (context, snapshot) => isDebug && snapshot.hasError
                  ? Container(
                      child: Text(snapshot.error.toString()),
                    )
                  : snapshot.hasData
                      ? MeasureSize(
                          onChange: (Size? size) {
                            // print('size ${size?.height}');
                            if (size != null) _post.extraCache.measureHeight = size.height;
                          },
                          child: snapshot.data)
                      : Container(
                          height: _post.extraCache.measureHeight,
                          child: Loading(),
                        ),

but now i can't find a entrypoint to do this.
How can i do this like before?

There is no direct replacement for this. The onErrorBuilder and onLoadingBuilder doesn't have access to the rendered widget anymore. If you need the height, it should be possible to measure the entire HtmlWidget.

but entire HtmlWidget have padding or margin, this make it unstable

The recent versions no longer have built-in paddings, I think it should be usable.
