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 chunk of generated code to the bottom of a given file.
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 chunk as a string. The tokens are represented as a `Map<String, dynamic>`
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.
