XDC3DART
XDC3DART SDK with support for smart contracts, XRC20 & XRC721.
Usage
XDC3DART is available through pub.dev. To install it, simply add the following command to your project:
dart pub add XDC3DART
then import modules per required
Import 'package:xdc3dart/xdc3dart.dart';
This SDK supports following Read & Write operations:-
| XRC20 Token: Read methods | XRC20 Token: Write methods |
| --- | --- |
| name() | approve(receiverAddress , amount) |
| symbol() | transfer(recipient, amount) |
| decimal() | transferFrom(sender, recipient, amount) |
| totalSupply() | increaseAllowance(spender, addedValue) |
| balanceOf(account) | decreaseAllowance(spender, subtractedValue) |
| allowance(owner, spender) | |
| | |
| XRC721 Token: Read methods | XRC721 Token: Write methods |
| ---- | ---- |
| name() | setApprovalForAll(operatorAddress, booleanValue) |
| symbol() | approve(receiverAddress , tokenId) |
| totalSupply() | transferFrom(recipient, tokenId) |
| balanceOf(owner address) | safeTransferFrom(spender, tokenId) |
| ownerOf(tokenId) | |
| tokenURI(tokenId) | |
| tokenByIndex(index) | |
| tokenOfOwnerByIndex(ownerAddress,index) | |
| supportInterface(interfaceId) | |
| getApproved(tokenId) | |
| isApprovedForAll(ownerAddress,operator) | |
| | |
Create an instance of XDC3DART. This will provide you access to a set of functions interacting with the blockchain.
final client = Web3Client(rpcUrl, Client(), socketConnector: () {
return IOWebSocketChannel.connect(wsUrl).cast<String>();
Example for XRC20
name() → string Returns the name of the token.
Future<String> name(String contractAdd) async {
final EthereumAddress contractAddr = EthereumAddress.fromHex(contractAdd);
final contract =
DeployedContract(ContractAbi.fromJson(abiFile, 'XRC20'), contractAddr);
final tokenName = contract.function('name');
final name =
await client.call(contract: contract, function: tokenName, params: []);
return '$name';
}
This example returns name of the specified address.
Example for XRC721
name() → string Returns the name of the token.
Future<String> name(token_address) async {
final EthereumAddress contractAddr = EthereumAddress.fromHex(token_address);
final contract =
DeployedContract(ContractAbi.fromJson(abiFile, 'XRC721'), contractAddr);
final tokenName = contract.function('name');
final name =
await client.call(contract: contract, function: tokenName, params: []);
return '$name';
}
