when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String transferTo,
    2. String amount,
    3. String tokenContract,
    4. String symbol,
    5. int decimals,
    )
)

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 transferTo,  String amount,  String tokenContract,  String symbol,  int decimals)  $default,) {final _that = this;
switch (_that) {
case _InitialTransactionMetadataCompat():
return $default(_that.transferTo,_that.amount,_that.tokenContract,_that.symbol,_that.decimals);}
}
