fromJson static method

AssistantAnswerDataSchema? fromJson(dynamic value)

Returns a new AssistantAnswerDataSchema instance and imports its values from value if it's a Map, null otherwise.

Implementation

// ignore: prefer_constructors_over_static_methods

    // Ensure that the map contains the required keys.
    // Note 1: the values aren't checked for validity beyond being non-null.
    // Note 2: this code is stripped in release mode!
