Usage #
A simple usage example:
import 'package:protondart/protondart.dart';

main() {
EOSClient client = EOSClient('https://eos.greymass.com', 'v1');

// Get EOS Node Info
client.getInfo().then((NodeInfo nodeInfo) {
print(nodeInfo);
});

// Get EOS Abi
client.getAbi('eosio.token').then((AbiResp abi) {
print(abi);
});

// Get EOS Raw Abi
client.getRawAbi('eosio.token').then((AbiResp abi) {
print(abi);
});

// Get EOS Raw code and Abi
client.getRawCodeAndAbi('eosio.token').then((AbiResp abi) {
print(abi);
});

// Get EOS Block Info
client.getBlock('298674').then((Block block) {
print(block);
});

// Get Account Info
client.getAccount('eosio.token').then((Account account) {
print(account);
});

// Get Account Actions
client.getActions('eosio.token', pos: -1, offset: -1).then((Actions actions) {
print(actions);
});

// Get Transaction
client
.getTransaction(
'83875faeb054ba20b20f392418e3a0002c4bb1c36cc4e3fde15cbd0963da8a15')
.then((TransactionBlock transaction) {
print(transaction);
});

// Get Accounts from public key
client
.getKeyAccounts('EOS8RWQpzzMi5uFXXXAChi4dHnyxMYKKdAQ3Y3pHQTrvhzGk95LbT')
.then((AccountNames accountNames) {
print(accountNames);
});

// Get currency balance
client
.getCurrencyBalance('parslseed123', 'newdexpocket')
.then((List<Holding> balance) {
print(balance);
});
