How can I read (from disk) and resize an image, in

Question

In Flutter/Dart, how can I perform the following 3 steps:

1. Read an image from disk,
2. Read its original dimensions (width and height),
3. Resize it.

Note: I must be able to display the final result with a regular Flutter Image widget.

CLARIFICATION: I don't want to save the image, but I do want to actually resize it in memory.

You can use the Image widget in the Scaffold widget,

First of all you need to create assets folder in the root and add an images folder, after that add,

    flutter:
      assets:
        - assets/images/

to the pubspec.yaml file, after that

new Image(
          image: AssetImage('assets/images/pizzaFont.png'),
          height: 12,
          width:12, ......
   )

You can use width and height to change the size of the image.
