First, you will need to add feedback_jira to your pubspec.yaml.

dependencies:
  flutter:
    sdk: flutter
  feedback_jira: x.y.z # use the latest version found on pub.dev

Then, run flutter pub get in your terminal.

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

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

void main() {
  runApp(
    BetterFeedback(
      child: const MyApp(),
    ),
  );
}

Provide a way to show the feedback panel by calling

BetterFeedback.of(context).showAndUploadToJira(
    domainName: 'domainName',
    apiToken: 'api-token',
);

Provide a way to hide the feedback panel by calling BetterFeedback.of(context).hide();
