AssetSource SpriteAnimationWidget.asset SpriteWidget.asset should support package args

[cruvie]

What could be improved

like flutter

 Image.asset(
              'assets/images/banner.png',
              package: 'demo',
            ),

we can specify package for asset so that we can make this pkg (include Image.asset )as a third-part pkg, which can be used as dependency for other project.

Why should this be improved

flame asset related function support package args

now when we use a pkg include such as AssetSource we will get error like this

[ERROR:flutter/runtime/dart_vm_initializer.cc(40)] Unhandled Exception: Unable to load asset: "assets/images/scenery/cliffs.png".
The asset does not exist or has empty data.

I agree, these classes should be more in line with how Flutter does it. We would have to start supporting the package argument in the Images class in some way.

As a workaround, you can either set the prefix of the static Flame.images cache to include your package:

Flame.images.prefix = 'packages/<your package>/.../`;

Or you could pass in a custom Images cache to the instance that you are creating:

SpriteWidget.asset(
  path: ...,
  images: Images(prefix: 'packages/<your package>/.../`),
);

The key here is to prefix the prefix with packages/, because that is the same thing as Flutter does under the hood when specifying the package argument on Image.asset.

@spydon thanks, the workaround works for me and looking forward to this feature
