when<TResult extends Object?> method

@optionalTypeArgs TResult when<TResult extends Object?>({ required TResult evm(String id, String chainId, String method, List<EvmTransactionParams> params,), required TResult solana(String id, String chainId, String method, SolanaTransactionParams params,), required TResult tron(String id, String chainId, String method, TronTransactionParams params,), })

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?>({required TResult Function( String id,  String chainId,  String method,  List<EvmTransactionParams> params)  evm,required TResult Function( String id,  String chainId,  String method,  SolanaTransactionParams params)  solana,required TResult Function( String id,  String chainId,  String method,  TronTransactionParams params)  tron,}) {final _that = this;
switch (_that) {
case EvmTransactionRpc():
return evm(_that.id,_that.chainId,_that.method,_that.params);case SolanaTransactionRpc():
return solana(_that.id,_that.chainId,_that.method,_that.params);case TronTransactionRpc():
return tron(_that.id,_that.chainId,_that.method,_that.params);}
}
