void main() {

}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        useMaterial3: false,
        primarySwatch: Colors.green,
      ),
      home: const HomePage(),
    );
  }
}

class HomePage extends StatefulWidget {
  const HomePage({super.key});

  @override
  HomePageState createState() => HomePageState();
}

class HomePageState extends State {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: const Text('Exmaple Chat'),
        ),
        body: Padding(
          padding: const EdgeInsets.all(10),
          child: ListView(
            children: const [
              InBubble(message: 'Oi bang'),

          ),
        )
    );
  }
}

class InBubble extends StatelessWidget {
  final String message;

  const InBubble({super.key, required this.message});

  @override
  Widget build(BuildContext context) {
    return Row(
      mainAxisAlignment: MainAxisAlignment.start,
      crossAxisAlignment: CrossAxisAlignment.start,
      children: [
        Transform(
          alignment: Alignment.center,
          transform: Matrix4.rotationY(math.pi),
          child: CustomPaint(
            painter: Triangle(Colors.grey.shade300),
          ),
        ),
        Flexible(
          child: Container(
            padding: const EdgeInsets.all(15),
            margin: const EdgeInsets.only(bottom: 5),
            decoration: BoxDecoration(
              color: Colors.grey.shade300,
              borderRadius: const BorderRadius.only(
                topRight: Radius.circular(19),
                bottomLeft: Radius.circular(19),
                bottomRight: Radius.circular(19),
              ),
            ),
            child: Text(
              message,
              style: const TextStyle(
                  color: Colors.black,
                  fontSize: 15
              ),
            ),
          ),
        ),
      ],
    );
  }
}

class OutBubble extends StatelessWidget {
  final String message;

  const OutBubble({super.key, required this.message});

  @override
  Widget build(BuildContext context) {
    return Row(
      mainAxisAlignment: MainAxisAlignment.end,
      crossAxisAlignment: CrossAxisAlignment.start,
      children: [
        Flexible(
          child: Container(
            padding: const EdgeInsets.all(15),
            margin: const EdgeInsets.only(bottom: 5),
            decoration: BoxDecoration(
              color: Colors.green.shade600,
              borderRadius: const BorderRadius.only(
                topLeft: Radius.circular(19),
                bottomLeft: Radius.circular(19),
                bottomRight: Radius.circular(19),
              ),
            ),
            child: Text(
              message,
              style: const TextStyle(
                  color: Colors.white,
                  fontSize: 15
              ),
            ),
          ),
        ),
        CustomPaint(
            painter: Triangle(
                Colors.green.shade600
            )
        ),
      ],
    );
  }
}

class Triangle extends CustomPainter {
  final Color backgroundColor;

  Triangle(this.backgroundColor);

  @override
  void paint(Canvas canvas, Size size) {
    var paint = Paint()..color = backgroundColor;

    var path = Path();
    path.lineTo(-5, 0);
    path.lineTo(0, 10);
    path.lineTo(5, 0);
    canvas.drawPath(path, paint);
  }

  @override
  bool shouldRepaint(CustomPainter oldDelegate) {
    return false;
  }
}

Untuk Output-nya nanti seperti ini:
