# 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?
|
||
|
|
```
