Dart SDK for [Nervos CKB](https://github.com/nervosnetwork/ckb)
## Prerequisites
- Dart 2.5 or later
## Installation
You should install dart firstly through [Dart](https://dart.dev/get-dart).
## Usage
### JSONRPC
A simple usage example of jsonrpc request which in `example/rpc.dart`:
```dart
main() async {
Api api = Api('http://localhost:8114', hasLogger: false);
String blockHash = await api.getBlockHash('0x2');
Block block = await api.getBlock(blockHash);
print(block.transactions[0].outputs[0].lock.toJson());
}
```
### Simple Wallet example
A simple usage example of `sendTransaction` which is in `example/wallet.dart`:
```dart
main() async {
api = Api(NODE_URL);
print('Before transferring, sender\'s balance: ${await getBalance(TestAddress)} CKB');
print('Before transferring, first receiver\'s balance: ${await getBalance(ReceiveAddresses[0])} CKB');
print('Before transferring, change address\'s balance: ${await getBalance(changeAddress)} CKB');
var hash = await sendCapacity(receivers, changeAddress);
print('Transaction hash: $hash');
// waiting transaction into block, sometimes you should wait more seconds
sleep(Duration(seconds: 30));
print('After transferring, sender\'s balance: ${await getBalance(TestAddress)} CKB');
print('After transferring, receiver\'s balance: ${await getBalance(ReceiveAddresses[0])} CKB');
print('After transferring, change address\'s balance: ${await getBalance(changeAddress)} CKB');
}
```
