Answer 1

[Edit 2021-12-02] I just found this https://pub.dev/packages/flutter_web3 , it is web only but seems to be compatible with WalletConnect QR codes connection, so it is probably worth a try.

Original answer:

I believe you can check out flutter_web3_provider but it only works for web.

I believe you can also use WalletConnect to support mobile wallets like these ones , but I haven't found a wrapper/implementation for flutter so you would need to implement that. But the good news is you would be able to use it in native apps. I see there is a react-native implementation so hopefully somebody will write the flutter implementation soon. You can support/like the request here .

Also you can directly sign and send transactions to an RPC server (a more direct gate to the blockchain) using web3dart , but of course you would need to ask for and/or store the user's private key, which is probably not what you want.
