# monero.dart
## Usage
```
monero:
git:
url: https://github.com/mrcyjanek/monero_c
ref: master
path: impls/monero.dart
```
```dart
import 'package: monero/monero.dart' as monero;
void main() {
final wm = monero.WalletManagerFactory_getWalletManager();
final w = monero.WalletManager_openWallet({...});
print(monero.Wallet_balance(w));
}
```
If you need more advanced usage, to for example use the code in an isolate, some workarounding is required **NOTE: from now on you manage your own memory partialy**.
Simplest example is this:
```dart
final addr = w.address;
final height = await Isolate.run(() async {
return monero.lib.MONERO_Wallet_daemonBlockChainHeight(Pointer.fromAddress(addr));
});
```
It gets even funnier when sending a transaction
```dart
final ptrAddr = xmrwPtr!.address;
final dstAddrPtr = txData.recipients!.first.address.toNativeUtf8().address;
final paymentAddrPtr = ''.toNativeUtf8().address;
final preferredInputsPtr = ''.toNativeUtf8().address;
final separatorPtr = ''.toNativeUtf8().address;
final amount = txData.recipients!.first.amount.raw.toInt();
final txPtrAddr = await Isolate.run(
() {
monero.lib ??= MoneroC(DynamicLibrary.open(monero.libPath));
final txPtr = monero.lib!.MONERO_Wallet_createTransaction(
Pointer.fromAddress(ptrAddr),
Pointer.fromAddress(dstAddrPtr).cast(),
Pointer.fromAddress(paymentAddrPtr).cast(),
amount, 0, 0, 0,
Pointer.fromAddress(preferredInputsPtr).cast(),
Pointer.fromAddress(separatorPtr).cast(),
);
// Nothing hits better than managing memory in GC language :)
return txPtr.address;
},
debugName: 'MONERO_Wallet_createTransaction',
);
final txPtr = Pointer.fromAddress(txPtrAddr).cast<Void>();
calloc.free(Pointer.fromAddress(dstAddrPtr));
calloc.free(Pointer.fromAddress(paymentAddrPtr));
calloc.free(Pointer.fromAddress(preferredInputsPtr));
calloc.free(Pointer.fromAddress(separatorPtr));
```
Async api will be made as a part of the generator update, too much effort under current design.
## Building
```bash
$ bash update_bindings.sh
$ # you are done, this is a library, what more did you expect?
```
