flutter_web3_provider 0.0.4

Flutter web web3 provider.

flutter_web3_provider

Flutter wrapper for using web3 providers, ie: accessing window.ethereum.

Getting Started

Add import import 'package:flutter_web3_provider/ethereum.dart';

Then you can access it just be using the ethereum variable.

if(ethereum != null){
    // then an ethereum provider was injected
    print(ethereum.selectedAddress);
}

Ask user to connect their wallet:

RaisedButton(
    child: Text("Connect Wallet"),
    onPressed: () async {
        var accounts = await promiseToFuture(
            ethereum.request(RequestParams(method: 'eth_requestAccounts')));
        print(accounts);
        String se = ethereum.selectedAddress;
        print("selectedAddress: $se");
        setState(() {
            selectedAddress = se;
        });
    },
)

Using ethers.js

Add ethers.js to web/index.html.

eg:

<script src="https://cdn.ethers.io/lib/ethers-5.0.umd.min.js" type="application/javascript"></script>

Then create an ethers Web3Provider:

Web3Provider web3 = Web3Provider(ethereum);

Then use it like you would in javascript.
