whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String name,
    2. String chainId,
    3. String currency,
    4. String rpcUrl,
    5. String explorerUrl,
    6. List<String> extraRpcUrls,
    7. bool isTestNetwork,
    8. String? chainIcon,
    )?
)

A variant of when that fallback to returning null

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return null;
}

Implementation

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? Function( String name,  String chainId,  String currency,  String rpcUrl,  String explorerUrl,  List<String> extraRpcUrls,  bool isTestNetwork,  String? chainIcon)?  $default,) {final _that = this;
switch (_that) {
case _ReownAppKitModalNetworkInfo() when $default != null:
return $default(_that.name,_that.chainId,_that.currency,_that.rpcUrl,_that.explorerUrl,_that.extraRpcUrls,_that.isTestNetwork,_that.chainIcon);case _:
  return null;

}
