Doesn't work in Chrome #122

Open gramster opened 1 year ago

Is it supposed to? That's not clear from the docs. I have this working as expected on iOS, but running in Chrome on MacOS I get an exception.

Code:

    screenshotController
        .captureFromWidget(
            Container(
                padding: const EdgeInsets.all(5.0),
                decoration: BoxDecoration(
                  border: Border.all(color: Colors.black, width: 2.0),                ),
                child: Column(
                    mainAxisAlignment: MainAxisAlignment.center,
                    children: [
                      Center(child: Text(_title)),
                      Center(
                          child: makeGridWidget(
                              forSharing: true)),
                    ])),
            delay: const Duration(milliseconds: 500))
        .then((capturedImage) {
            ...

makeGridWidget returns a GridView where each child is one of these:

SizedBox(
          width: 50,
          height: 50,
          child: DecoratedBox(
            decoration: BoxDecoration(color: color, border: border),
            child: Center(
                child: Text(txt,
                    textAlign: TextAlign.center,
                    style: const TextStyle(color: Colors.black))),
          ),
        ))

Result:

Flutter Web Bootstrap: Programmatic
══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════
The following assertion was thrown building RawScrollbar(dirty, dependencies: [Directionality],
state: RawScrollbarState<RawScrollbar>#05aaa(tickers: tracking 1 ticker)):
No MediaQuery widget ancestor found.
RawScrollbar widgets require a MediaQuery widget ancestor.
The specific widget that could not find a MediaQuery ancestor was:
  RawScrollbar
The ownership chain for the affected widget is: "RawScrollbar ← Scrollable ← GridView ← Center ←
  Column ← Padding ← DecoratedBox ← Container ← Directionality ←
  RenderObjectToWidgetAdapter<RenderBox>-[GlobalObjectKey RenderRepaintBoundary#5b526]"
No MediaQuery ancestor could be found starting from the context that was passed to MediaQuery.of().
This can happen because you have not added a WidgetsApp, CupertinoApp, or MaterialApp widget (those
widgets introduce a MediaQuery), or it can happen if the context you use comes from a widget above
those widgets.
The relevant error-causing widget was:
GridView
When the exception was thrown, this was the stack:
