## Description This improves defaults generation with logging, stats, and token validation. This PR includes these changes: * introduce `TokenLogger`, with a verbose mode * prints versions and tokens usage to the console * outputs `generated/used_tokens.csv`, a list of all used tokens, for use by Google * find token files in `data` automatically * hide tokens `Map` * tokens can be obtained using existing resolvers (e.g. `color`, `shape`), or directly through `getToken`. * tokens can be checked for existence with `tokenAvailable` * remove version from template, since the tokens are aggregated and multiple versions are possible (as is the case currently), it does not make sense to attribute a single version * improve documentation ## Related Issues - Fixes https://github.com/flutter/flutter/issues/122602 ## Tests - Added tests for `TokenLogger` - Regenerated tokens, no-op except version removal ## Future work A future PR should replace or remove the following invalid tokens usages <img width="578" alt="image" src="https://github.com/flutter/flutter/assets/6655696/b6f9e5a7-523f-4f72-94f9-1b0bf4cc9f00">
