patternProperties property
A map of the property patterns of the object to the nested Schemas for those properties.
For example, to define a schema where any property name starting with "x-" should have a string value:
final schema = ObjectSchema(patternProperties: {r'^x-': Schema.string()});
Implementation
Map<String, Schema>? get patternProperties =>
(_value['patternProperties'] as Map?)?.cast<String, Schema>();
