fromJson method

@override void fromJson(dynamic json)

Deserializes JSON data into this model instance.

This method populates the model's fields from the provided JSON data and handles error/warning/information messages from the server response. It automatically:

• Extracts general errors, warnings, and informational messages
• Maps field-specific errors, warnings, and informations
• Deserializes all field values from the JSON map
• Assigns validation messages to the corresponding fields

Parameters:

• json: The JSON data to deserialize. Can be a Map<String, dynamic> or any other type (in which case deserialization is skipped).

Example:

final user = UserModel();
user.fromJson({
  'name': 'John Doe',
  'age': 30,
  'errors': {'email': 'Invalid email format'},
  'generalErrors': ['Account verification required']
});

Implementation

@override
void fromJson(json) {
  super.fromJson(json);
  if (json is Map<String, dynamic>) {
    if (json.containsKey("displayName") &&
        json["displayName"] is String &&
        json["displayName"].isNotEmpty &&
        name.value.isEmpty) {
      name.value = json["displayName"];
    }
  }
}
