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'
