import 'package:eth_url_parser/eth_url_parser.dart';

final Map<String, dynamic> parameters = EthUrlParser.parse(
  'ethereum:0x1234DEADBEEF5678ABCD1234DEADBEEF5678ABCD',
);
print('${parameters['targetAddress']}');
// '0x1234DEADBEEF5678ABCD1234DEADBEEF5678ABCD'

final String uri = EthUrlParser.build(
  targetAddress: '0x1234DEADBEEF5678ABCD1234DEADBEEF5678ABCD',
  functionName: 'transfer',
  parameters: {
    'address': '0x12345',
