when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String name,
    2. String welcomeMessage,
    3. String systemInstruction,
    4. String? fontFamily,
    5. String? color,
    6. String? avatar,
    7. FabConfiguration? fabConfiguration,
    )
)

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}

Implementation

@optionalTypeArgs TResult when<TResult extends Object?>(TResult Function( String name, @JsonKey(name: 'welcome_message')  String welcomeMessage, @JsonKey(name: 'system_instruction')  String systemInstruction,  String? fontFamily,  String? color,  String? avatar, @JsonKey(name: 'fab_configuration')  FabConfiguration? fabConfiguration)  $default,) {final _that = this;
switch (_that) {
case _RemoteConfig():
return $default(_that.name,_that.welcomeMessage,_that.systemInstruction,_that.fontFamily,_that.color,_that.avatar,_that.fabConfiguration);case _:
  throw StateError('Unexpected subclass');

}
