IntelliJ IDEA import javax.imageio.ImageIO package

This question already has an answer here:

• Can't import javax.imageio.ImageIO in Android application 1 answer

Running a Flutter project has worked fine until adding a call to ImageIO within a dart package java file ImagePickerPlugin.java. The import is at the top and command-click shows the class in the IDE, but compiling fails.

try {
  Image image = ImageIO.read(sourceimage);
} catch (IOException e) {
  e.printStackTrace();
}

Comile error:

import javax.imageio.ImageIO;

Anybody have any issues when changing dart packages with IntelliJ IDEA? Thanks

This turned out to not be an issue with importing, more that ImageIO isn't available on Android. Found this out via:

Library Java can't resolve in Android Studio 3.1

Have gone another route and all working now.
