AutoSizeGroup doesn't work on web/Android

[MarcVanDaele90]

Steps to Reproduce

• create a project with the code below
• build it using flutter build web
• put the build/web directory on a webserver
• access this url from both chrome/Linux (works fine) and from chrome/Android (does not work)

The code below runs fine

• on web(chrome)/Linux
• on Android (as app)
• but NOT on web(chrome)/Android
  In the later case, the autosizing does not seem to work.

Code sample

      body: Row(
        children:[
          Spacer(flex:3),
          Expanded(child: Card(child: AutoSizeText("aaa", group: autoSizeGroup, maxLines:1, minFontSize: 6, style: textStyle))),
          Expanded(child: Card(child: AutoSizeText("somewhat longer", group: autoSizeGroup, maxLines: 1, minFontSize: 6, style: textStyle))),
          Spacer(flex:3)
        ]
      ),

This is apparently triggered by flutter/flutter#65940

I have a temporary workaround (which is inefficient and probably incomplete but it might be helpful to others).

I replaced textpainter.didExceedMaxLines with

    final textPainter2 = TextPainter(
      text: text,
      textAlign: widget.textAlign ?? TextAlign.left,
      textDirection: widget.textDirection ?? TextDirection.ltr,
      textScaleFactor: scale,
      maxLines: maxLines==null?maxLines:maxLines+1,
      locale: widget.locale,
      strutStyle: widget.strutStyle,
    );
    textPainter2.layout(maxWidth: constraints.maxWidth);

    bool didExceedMaxLines = textPainter2.height>textPainter.height;

This fixes the issue on my side (note that I didn't touch wordWrapTextPainter because I didn't need this right now)

It seems flutter/engine#34085 PR did fix the issue it is available in Flutter 3.7.0 stable release.
