extractFromSources function

DartProject extractFromSources(Map<String, String> sources, { FieldRename globalRename = FieldRename.none, })

Extracts models from in-memory sources keyed by relative path.

Implementation

DartProject extractFromSources(

      path: e.key,
      throwIfDiagnostics: false,
    );
    units[e.key] = (result.unit, result.lineInfo);
  }

  // Pass 1: enums and the names of every class with a fromJson.

        modelNames.add(decl.namePart.typeName.lexeme);
