[Feature] Add package_name field to be able to use assets inside packages without assigning package name to every image widget.

Feature: Add package_name Field to flutter_assets configs for Asset Management

Explanation:

In Flutter, when using assets from a package, developers currently need to specify the package name for each asset individually in the Image widget or similar widgets. This can be repetitive and inefficient, especially when using multiple assets from the same package.

The proposed feature introduces a package_name field that can be added to the pubspec.yaml file under the flutter_assets: section. This field would allow developers to define the package name globally. As a result, assets could be used without repeatedly specifying the package name, improving code cleanliness and reducing redundancy.

For example, instead of writing:

Image.asset('assets/images/icon.png', package: 'my_package')

each time an asset is used, the package_name could be set once in the pubspec.yaml:

flutter_assets:
  package_name: my_package

Then, this would resolve to:

String icon = 'packages/my_package/assets/images/icon.png';

Nice suggestion.
