# SnarkJS within Flutter

An attempt to use SnarkJS within Flutter WebView.

- [WebView Tutorial](https://codelabs.developers.google.com/codelabs/flutter-webview#0)

- [SnarkJS in Browser](https://github.com/iden3/snarkjs#in-the-browser)

The example circuit used within `multiplier_3` is simply a circuit to compute the multiplication of 3 numbers.

```js

// input signals

{

  "in": [3, 7, 11]

}

// output signals

{

  "out": 231

}

```

The provided prover key & verification key is of a PLONK proof system. PTAU used is for BN128 by [Polygon Hermez](powersOfTau28_hez_final_08.ptau) (less than $2^8$ constraints in this one).

Note that there is an [issue](https://github.com/iden3/snarkjs/issues/317) with browser code of Snarkjs right now, until that is fixed we are using version `0.5.x`.
