Utility to convert an upper or lower case Web3/Ethereum address to a checksum address (EIP55).
In your pubspec.yaml
file add:
dependencies:
eip55: any
Import the package:
import 'package:eip55/eip55.dart';
Then:
final eip55Address = toEIP55Address('0x68775f2604f67a571f626c99ae4eb252b579dcd7');
Alternately:
final eip55Address = toChecksumAddress('0x68775f2604f67a571f626c99ae4eb252b579dcd7');
