            You can use the overrides parameter. It's used after all contract function arguments.

            In your case, the contract function has 0 arguments so the overrides is on position 1.

            How can you sign hyperledger-sawtooth transactions using metamask keys?
            Asked 2020-Nov-03 at 15:45

            Hyperledger sawtooth uses secp256k1 ECDSA to sign transactions: https://sawtooth.hyperledger.org/docs/core/releases/1.2.5/_autogen/txn_submit_tutorial.html?highlight=transaction%20sign

            And aparently ethereum uses the same type of signature: https://hackernoon.com/a-closer-look-at-ethereum-signatures-5784c14abecc

            Thus, it would seem that because Metamask is used with Ethereum it would also work with sawtooth. However, I haven't found examples of this, and although I've tried signing transactions with web3.js and ethers.js with Metamask those signatures get rejected by Sawtooth.

            Use JS library in Flutter
            Asked 2020-May-15 at 00:54

            I am trying to use Ether JS in my Flutter application. I know that it is not directly supported and even the existing implementations are not really well documented.

            Is there any way I can use this library in my Flutter application for Android and iOS? Any other alternative suggestion is also welcome.

            I have tried js.dart but could not figure out how to use it. I am not even sure if it is the right choice for this scenario.

            I have also tried Flutter WebView Plugin.

            Honestly, if you're new to Flutter, Dart, and JS you are going to have some trouble with this unless you're willing to invest a fair amount of time. It does depend on what exactly you're trying to make with the Ether JS library, but in general you're going to have a hard time integrating it with flutter. There is an Ethereum package but it seems much narrower in scope than the ether.js library you've been looking at - it mostly seems focused on communication with the RPC api rather than dealing with wallets etc.

            If you're dead set on using Flutter, your best bet would be to use Android & iOS specific libraries to do the actual ethereum stuff and to communicate through Platform Channels to a common api in your dart code. This could be a significant undertaking depending on how much of the API you need to expose, especially for someone new to flutter/dart and possibly to android/ios development as well. This will be much more performant than communicating back and forth with javascript running in a webview though, and realistically probably easier to code as well because flutter doesn't really have any good mechanisms for calling js code right now.

            There is another option - to use a different client UI framework entirely. React native might do everything you need and has the advantage of being in Javascript so it can most likely integrate the Ether.js library easily, although I can't guarantee that it will actually fully support the ether.js library (its runtime might not have the necessary crypto extensions for example).
