ContractSchemas class final

The API documents of the repository, loaded once per isolate.

Validates the JSON Schema subset the documents use: type, required, properties, additionalProperties, enum, items, $ref, allOf, oneOf with a discriminator, format for uuid and date-time, and the bounds minimum, maximum, minLength, maxLength, minItems, maxItems and pattern. Every other keyword is ignored. JSON null never validates, because the API has no null (ADR 0053).

Example:

final contract = ContractSchemas.load();
final problems = contract.validate({'id': 'x'}, 'Thread');
// [/id: invalid_format (uuid), /channel_id: required (...), ...]
