## Token Defaults Generator
|
|
|
|
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.
|
|
|
|
## Usage
|
|
Run this program from the root of the git repository:
|
|
```
|
|
dart dev/tools/gen_defaults/bin/gen_defaults.dart
|
|
```
|
|
|
|
## Templates
|
|
|
|
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.
|
|
|
|
See `lib/fab_template.dart` for an example that generates defaults for the
|
|
Floating Action Button.
