Feedback SDK for Flutter apps

A dedicated Flutter package with an inherited controller, a floating launcher, and a bottom-sheet feedback flow that talks to the same Upstep project as your web app.

Setup steps

1
Install: flutter pub add upstep_flutter
2
Wrap your app near the root with Upstep(apiKey: ...)
3
Keep FeedbackSheet() and FeedbackButton() mounted in the same subtree, or open the sheet from your own button via Upstep.of(context).openSheet()

Code

dart

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

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Upstep(
        apiKey: "upstep_xxx",
        child: Scaffold(
          appBar: AppBar(title: const Text("Upstep demo")),
          body: Stack(
            children: const [
              Center(child: Text("Your app")),
              FeedbackSheet(),
              FeedbackButton(),
            ],
          ),
        ),
      ),
    );
  }
}

The Flutter SDK persists an anonymous visitor id locally for vote dedupe, then switches cleanly to userId when you call identify() after login.

Every Upstep project ships a built-in MCP server. Once feedback starts flowing in from Flutter, Claude Code, Cursor, or any MCP client can list it, triage it, and file Dev-only tasks, without leaving your editor.
