参数类型 &#39;Future<Widget> &#39; 不能分配给参数类型 &#39;Widget&#39;.dart

Question

Here I have to use pdfImageFromImageProvider function to stateless widget . So, Is it possible to resolve this issue using stateless widget?

Future<Widget> getWidgetAsync(double size) async {
PdfImage val = await pdfImageFromImageProvider(
  pdf: pdf.document,
  image: fw.AssetImage('assets/' + iconPath),
);

return Container(
  width: size,
  height: size,
  decoration: BoxDecoration(
    color: layoutbg,
    shape: BoxShape.circle,
  ),
  child: Image(val),
);

}

Answer 1

Your method must return Future<Widget> , as I'm understanding your question's title is your error, its mean that you returning a Widget not Future<Widget> . To do that, you should wrap your widget inside the Future like this:

Future<Widget> getWidgetAsync(double size) async {
PdfImage val = await pdfImageFromImageProvider(
  pdf: pdf.document,
  image: fw.AssetImage('assets/' + iconPath),
);

return Future.value(Container(
  width: size,
  height: size,
  decoration: BoxDecoration(
    color: layoutbg,
    shape: BoxShape.circle,
  ),
  child: Image(val),
));

Hope this will work.
