• assets.yaml
• assets-<platform>.yaml
• assets-<flavor>.yaml (only for local package)
• assets-<platform>-<flavor>.yaml (only for local package)

assets, fonts and use-material-design parameters are overridden at each loaded file.

When an assets file is not present, the next one is loaded without overriding parameters from previous steps.

Assets file format is the same as pubspec.yaml.
