In the app development battleground, creating a seamless user interface is just half the job — you must also see how users are using your app. Is everything going to plan? Are they getting stuck on a screen? Are they dropping off halfway? That's where Microsoft Clarity can help.

Microsoft Clarity is a free, simple-to-implement behavior analytics solution built by Microsoft that gives session recordings, heatmaps, and user journey tracking to enable developers and product teams to see precisely how users are interacting with their websites and apps.

From trying to minimize churn, to enhancing UI/UX, or debugging unforeseen behavior — Clarity gives strong visual feedback that standard analytics tools typically fail to do.

In this blog post, we will find out how to use Microsoft Clarity in a Flutter application.

Getting started with Clarity

To get started we need to first register in the Clarity dashboard and create a project.

Sign up for Clarity

1. Onboarding Clarity is free and easy. If you're new to Clarity, start by signing up. Go to https://clarity.microsoft.com/ and select Sign up/Sign in using Microsoft account/Google/Facebook.

2. Upon successful sign in you will navigate to the Projects screen.

Add a new project

1. Select New project to start adding a project.

2. Go to the Mobile tab. Choose Flutter in the platform and enter the Project Name with industry. Select Add new project once done.

3. Once the project is created you can find the Clarity project ID. Save this ID for later use.

Integration in Flutter

Add Dependency 

Add the clarity_flutter dependency to your pubspec.yaml file.

dependencies:
  clarity_flutter: <latest release>

Import the Package 

Import the clarity_flutter package in your main.dart file.

import 'package:clarity_flutter/clarity_flutter.dart';

Initialize and Wrap Your App 

Initialize the ClarityConfig object and wrap your app with the ClarityWidget widget.

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

void main() {
  final config = ClarityConfig(
    projectId: "your_project_id" Paste your clarity project code
  );

  runApp(ClarityWidget(
    app: MyApp(),
    clarityConfig: config,
  ));
}

That’s it you can now run the application and get the analytics in Clarity dashboard.

Masking Widgets

The Clarity Flutter SDK provides masking widgets to mask sensitive information in your app. These widgets are ClarityMask and ClarityUnmask.

1. ClarityMask 

Use ClarityMask to mask widgets containing sensitive information.

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

class MaskedWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ClarityMask(
      child: Text('Sensitive Information'),
    );
  }
}

2. ClarityUnmask

Use ClarityUnmask to unmask widgets within a masked area.

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

class UnmaskedWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ClarityUnmask(
      child: Text('Non-sensitive Information'),
    );
  }
}
