- EtherUnit unit,
- dynamic amount
Constructs an amount of Ether by a unit and its amount. amount

Implementation
factory EtherAmount.fromUnitAndValue(EtherUnit unit, dynamic amount) {

parsedAmount = BigInt.from(amount);
} else if (amount is String) {
parsedAmount = BigInt.parse(amount);
} else {
throw ArgumentError('Invalid type, must be BigInt, string or int');
}
return EtherAmount.inWei(parsedAmount * _factors[unit]!);
