Wont compile on dev channel about flutter_tflite HOT 6 CLOSED

import 'package:flutter/painting.dart';

And then change the 'new fileimage'function to

new FileImage(image)
    .resolve(new ImageConfiguration())
    .addListener( ((ImageInfo info, bool synchronousCall) {
          setState(() {
            _imageHeight = info.image.height.toDouble();
            _imageWidth = info.image.width.toDouble();
          });
        }) as ImageStreamListener);

seems to solve this one.

Yes. Looks like they changed addListener interface in painting library.

Casting the type to ImageStreamListener as @tnup suggested should be the solution.

I am receiving the following error.
Exception has occurred.
_CastError (type '(ImageInfo, bool) => Null' is not a subtype of type 'ImageStreamListener' in type cast)

try this @PrinceP

new FileImage(image)
    .resolve(new ImageConfiguration())
    .addListener( new ImageStreamListener((ImageInfo info, bool synchronousCall) {
          setState(() {
            _imageHeight = info.image.height.toDouble();
            _imageWidth = info.image.width.toDouble();
          });
        }) as ImageStreamListener);

    setState(() {
      _image = image;
      _busy = false;
    });
  }

double cast, but works.

@tnup Couldn't understand but this works. Thanks
