# deleteFlow

Lets a sender delete an existing stream to a receiver

```javascript
//load the token you'd like to use like this 
//note that tokens may be loaded by symbol or by address
const daix = await sf.loadSuperToken("DAIx");

let flowOp = daix.deleteFlow({
  sender: string,
  receiver: string,
  userData?: string
});

await flowOp.exec( <<ethers signer>> ); // should have same address as sender
```
