How to Make a Live Streaming App with Flutter

Real-Time Chat

class LiveChat extends StatefulWidget {
  final String streamId;
  const LiveChat({super.key, required this.streamId});
  @override State createState() => _LiveChatState();
}

class _LiveChatState extends State {
  final _messages = [];
  final _ctrl = TextEditingController();
  WebSocketChannel? _channel;

  @override
  void initState() {
    super.initState();
    _connect();
  }

  void _connect() {
    _channel = WebSocketChannel.connect(
      Uri.parse('wss://chat.example.com/stream/\${widget.streamId}'),
    );
    _channel!.stream.listen((data) {
      final msg = ChatMessage.fromJson(jsonDecode(data as String));
      setState(() => _messages.add(msg));
    });
  }

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        Expanded(
          child: ListView.builder(
            reverse: true,
            itemCount: _messages.length,
            itemBuilder: (ctx, i) {
              final msg = _messages[_messages.length - 1 - i];
              return ListTile(
                dense: true,
                leading: CircleAvatar(
                  radius: 12,
                  child: Text(msg.username[0], style: const TextStyle(fontSize: 10)),
                ),
                title: Text('\${msg.username}: \${msg.text}'),
              );
            },
          ),
        ),
        Padding(
          padding: const EdgeInsets.all(8),
          child: Row(
            children: [
              Expanded(
                child: TextField(
                  controller: _ctrl,
                  decoration: InputDecoration(
                    hintText: 'Type a message...',
                    border: OutlineInputBorder(borderRadius: BorderRadius.circular(20)),
                    contentPadding: const EdgeInsets.symmetric(horizontal: 16, vertical: 8),
                  ),
                ),
              ),
              IconButton(
                icon: const Icon(Icons.send),
                onPressed: () {
                  if (_ctrl.text.isNotEmpty) {
                    _channel?.sink.add(jsonEncode({'text': _ctrl.text}));
                    _ctrl.clear();
                  }
                },
              ),
            ],
          ),
        ),
      ],
    );
  }

  @override
  void dispose() {
    _channel?.sink.close();
    super.dispose();
  }
}

class ChatMessage {
  final String username, text;
  ChatMessage({required this.username, required this.text});
  factory ChatMessage.fromJson(Map j) => ChatMessage(
    username: j['username'], text: j['text']);
}

UI & UX Suggestions

Use a dark theme (#0d1117), purple accent for alerts, red for live indicator colour palette to match the app's purpose. Keep the navigation simple — a bottom nav bar or a single-scroll layout works best for this type of app. Make sure every interaction provides haptic or visual feedback so the app feels responsive and polished.
