Pub GitHub Workflow Status code coverage

A Flutter package for getting better feedback. It allows the user to give interactive feedback directly in the app. Get it on!



Often times it is quite hard to understand the users issues with an app. This package aims to support the developer by making it easier for the user to provide good and helpful feedback. Thus this library tries to be pretty easy to use by the user and lightweight to integrate for the developer.


First, you will need to add feedback to your pubspec.yaml:

    sdk: flutter
  feedback: 0.3.0 # use the latest version found on

Then, run flutter packages get in your terminal.

Getting Started

Just wrap your app in a BetterFeedback widget and supply an onFeedback function. The function gets called when the user submits his feedback. To show the feedback view just call BetterFeedback.of(context).show();

import 'dart:typed_data';
import 'package:feedback/feedback.dart';
import 'package:flutter/material.dart';

void main() {
      child: const MyApp(),
      onFeedback: (
        BuildContext context,
        String feedbackText, // the feedback from the user
        Uint8List feedbackScreenshot, // raw png encoded image data
      ) {
        // TODO: upload to feedback to server or let the user share his feedback 

Upload feedback

To upload the feedback you should use, for example, a MultipartRequest.


import 'dart:typed_data';
import 'package:feedback/feedback.dart';
import 'package:flutter/material.dart';

void main() {
      // You can customize the background color, ...
      backgroundColor: Colors.grey,
      // ... the colors with which the user can draw..
      drawColors: [,,, Colors.yellow],
      // ... and the language used by BetterFeedback.
      // You can pass any subclass of [FeedbackTranslation] to change the 
      // the text.
      translation: DeTranslation(),
      child: MyApp(),
      onFeedback: alertFeedbackFunction,

For development purposes this library includes two methods which can be passed directly as onFeedback-callback.

  • alertFeedbackFunction which shows a simple alert dialog with the image and the corresponding user feedback.
  • consoleFeedbackFunction which prints the user feedback and the image size with print to console.

Tips, tricks and usage scenarios

  • You can combine this with device_info and package_info to get additional information about the users environment to better understand his feedback and debug his issues.
  • You can record the users navigation with a NavigatorObserver and send it as an addition to the feedback of the user. This way you know how the user got to the location shown in the screenshot.
  • Use it as a view for Sentrys user feedback to collect additional user information upon hitting an error.

Known Issues and limitations

  • Some draggable widgets like ReorderableListView look strange while dragging.
  • Platform views are invisible in screenshots (like webview or Google Maps)
  • Why does the content of my Scaffold change (gets repositioned upwards) while I'm writing my feedback?
    • Probably because Scaffold.resizeToAvoidBottomInset is set to true. You could set it to false while the user provides feedback.

A personal note

Let me know if you are using this in your app, I would love to see it.
