Script that generates widget component theme data defaults based on the Material Token database. These tokens were extracted into a JSON file from an internal Google database.
Run this program from the root of the git repository:
There is a template file for every component that needs defaults from the token database. These templates are implemented as subclasses of
TokenTemplate. This base class provides some utilities and a structure for adding a new block of generated code to the bottom of a given file.
Templates need to override the
generate method to provide the generated code block as a string. The tokens are represented as a
Map<String, dynamic> that is loaded from
data/material-tokens.json. Templates can look up whatever properties are needed in this structure to provide the properties needed for the component.
lib/fab_template.dart for an example that generates defaults for the Floating Action Button.
