Integration with build

[dotdoom]

build offers a platform to perform code generation and other build related tasks. For example, it's used by built_value package to generate code.

The beauty of using build is that it's a single point of entry to generate artifacts necessary to compile and build a project, which simplifies CI/CD or manual work by offering a single interface.

If this package will integrate with build graph, it would build icons as a part of pub run build_runner build or even automatically at compile time via less known flutter generate
