eth_url_parser #

eth_url_parser is translated from https://www.npmjs.com/package/eth-url-parser

Module that supports parsing / parsing of all the different ethereum standard urls: ERC-681 and ERC-831

This module contains two functions:

EthUrlParser.parse(string) #

Takes in a string of an Ethereum URL and returns an object matching that URL according to the previously mentioned standards The returned object looks like this:

TransactionRequest(
  scheme: 'ethereum',
  targetAddress: '0x1234DEADBEEF5678ABCD1234DEADBEEF5678ABCD', // ENS names are also supported!
  functionName: 'transfer',
  chainId: 1,
  parameters: {
    'value': '2014000000000000000', // (in WEI)
    'gas': '45000', // can be also gasLimit
    'gasPrice': '50',
  },
)

EthUrlParser.build(TransactionRequest transactionRequest) #

Takes in an object representing the different parts of the ethereum url and returns a string representing a valid ethereum url

Usage #

import 'package:eth_url_parser/eth_url_parser.dart';

final TransactionRequest transactionRequest = EthUrlParser.parse(
  'ethereum:0x1234DEADBEEF5678ABCD1234DEADBEEF5678ABCD',
);
print(transactionRequest.targetAddress);
// '0x1234DEADBEEF5678ABCD1234DEADBEEF5678ABCD'

final String uri = EthUrlParser.build(
  TransactionRequest(
    targetAddress: '0x1234DEADBEEF5678ABCD1234DEADBEEF5678ABCD',
    functionName: 'transfer',
    parameters: {
      'address': '0x12345',
      'uint256': '1',
    },
  ),
);
print('$uri');
// 'ethereum:0x1234DEADBEEF5678ABCD1234DEADBEEF5678ABCD/transfer?address=0x12345&uint256=1'
