Setup

Connect your wallet application (e.g. Phantom) and SolanaWalletAdapter to the same network. The wallet application may not support localhost.

Example: Authorize

import 'package:flutter/material.dart';
import 'package:solana_wallet_adapter/solana_wallet_adapter.dart';

void main() {
  runApp(const MaterialApp(
    home: Scaffold(
      body: Center(
        child: AuthorizeButton(),
      ),
    ),
  ));
}

// 1. Create instance of [SolanaWalletAdapter].
final adapter = SolanaWalletAdapter(
  const AppIdentity(),
  // NOTE: CONNECT THE WALLET APPLICATION 
  //       TO THE SAME NETWORK.
  cluster: Cluster.devnet,
);

class AuthorizeButton extends StatefulWidget {
  const AuthorizeButton({super.key});
  @override
  State<AuthorizeButton> createState() => _AuthorizeButtonState();
}

class _AuthorizeButtonState extends State<AuthorizeButton> {
  Object? _output;
  @override
  Widget build(BuildContext context) {
    return Column(
      mainAxisAlignment: MainAxisAlignment.center,
      children: [
        TextButton(
          onPressed: () {
            // 2. Authorize application with wallet.
            adapter.authorize()
              .then((result) => setState(() => _output = result.toJson()))
              .catchError((error) => setState(() => _output = error));
          },
          child: const Text('Authorize'),
        ),
        if (_output != null)
          Text(_output.toString()),
      ],
    );
  }
}
