Flutter Session Replay & Recording for Apps: UXCam

Summary - Flutter session replay

What is a session replay?

A session replay is a visual, step-by-step reconstruction of how users navigate your app. It captures every tap, swipe, scroll, and screen transition so teams can see the real user journey, not just metrics.

Instead of guessing where friction happens, session replay lets you watch the actual experience: hesitation before tapping a button, broken flows, confusing UI elements, or moments of frustration. For Flutter apps, this is especially important because widgets can behave differently across devices.

UXCam turns these interactions into secure, privacy-safe recordings that help teams debug issues, improve flows, and build better features with confidence.

How session replay works in Flutter

Session replay in Flutter works differently compared to native iOS or Android apps because Flutter uses a single UI rendering engine. UXCam captures replay data by recording:

• The widget tree structure: To understand what UI elements were visible at each moment.

• Frame-by-frame visual changes: Capturing updates as the Flutter engine rebuilds widgets.

• User gestures: Taps, long presses, swipes, scrolls, back navigation.

• Navigation events: Route changes, bottom bar switches, modal openings.

• App lifecycle events: Foreground, background, resume.

UXCam compresses this interaction data efficiently before sending it to the dashboard, ensuring performance remains smooth. Sensitive fields (e.g., passwords, card details) are automatically masked to protect user privacy.

How to set up session replay for Flutter apps with UXCam

1. Add UXCam to your flutter project: Install the UXCam Flutter package and add it to your pubspec.yaml.

2. Import and initialize UXCam: Place the initialization code in your main.dart file and add your UXCam API key. Once enabled, UXCam automatically records sessions, no event tagging required.

3. Run your app: Launch your Flutter app. Your first sessions will appear on the UXCam dashboard within minutes.

4. Explore and customize: Use the UXCam dashboard to view replays, configure masking, set up custom events, and refine filters.

Overview of UXCam’s session replay for Flutter

UXCam provides high-quality session replays backed by powerful filters, tagging, notes, and event analytics. Teams can quickly find sessions that matter, watch only the relevant moments, and collaborate on issues directly inside the dashboard.

Every session includes essential user details, such as, location, device, crashes, UI freezes, and custom properties, giving teams full context before reviewing the replay.

Key components of a UXCam session

Here are the details you’ll find in a UXCam session recording

Session information bar

The top panel of the replay shows user identification (Alias or User ID), location, device, session time, and labels. If a crash or UI freeze occurs, UXCam flags it automatically. Clicking the indicator reveals technical logs so developers can diagnose the issue quickly.

Detailed timeline (Activity Tab)

UXCam’s timeline visualizes the full journey across screens and actions. Blocks represent screens, and each block shows how long a user stayed. Clicking any interaction jumps directly to that point in the replay, making it easy to investigate friction. Smart event icons highlight taps, gestures, rage taps, or custom events, allowing you to navigate sessions without watching the entire recording.

Advanced filters to find key sessions

UXCam’s filters help you surface the right sessions instantly. You can narrow results by:

• User actions (taps, swipes, scrolls)

• Technical issues (crashes, freezes)

• User attributes (device, location, OS)

• Session characteristics (duration, engagement level)

You can also exclude internal testers and filter for frustration signals like rage taps or dead taps. This helps Flutter teams understand exactly where usability issues occur. 

Tag sessions

UXCam enables you to easily identify and investigate user issues with its tagging feature. By adding custom tags, like "crash" or a specific error message, it's easier to filter through high volumes of sessions for the ones that contain relevant information about potential problems your users are experiencing. Additionally, it improves cross-functional collaboration between product, design, QA, and engineering teams helping stay aligned on the same issue. 

Leave notes to align your team

With notes, you can highlight issues that a user may have experienced or provide suggestions for improvement directly on specific parts of replay sessions. Plus, team collaboration is made simpler as well; share your notes with other members and give them meaningful context about observed behaviors, even if they're remote.

Analyze events

Event analysis lets you jump from a custom event directly to the moment it happened in the replay. This gives you faster insight into user behavior around key actions, purchases, taps, onboarding steps, failed attempts, etc. You can watch sessions tied to that event or pivot into reports to analyze trends. This dual functionality empowers you to gain insights into user interactions with specific events in their app swiftly and effectively. 

Security and privacy features

UXCam is a premier app analytics tool committed to upholding the highest standard of user data privacy and security. With the global average cost of a data breach now reaching $4.45 million, robust compliance and built-in privacy protections are no longer optional, they’re essential safeguards for every organization.

To ensure users' personal information remains safe, we have implemented industry-leading features tailored for session replay, like masking sensitive data. Additionally, we are compliant with GDPR and CCPA, which are leading data regulations for user protection, ensuring your UX research activities remain secure and transparent. All this combines so you can be assured that user data always remains safe in its handling at all times.

Performance impact and optimization of UXCam for Flutter apps

Many developers wonder:

“Will session replay slow down my Flutter app?”

UXCam is designed to be lightweight and optimized specifically for Flutter’s rendering pipeline. Here’s what you should know:

Minimal performance footprint

UXCam captures UI frames and gesture data without blocking the UI thread or slowing animations. Most Flutter apps see no noticeable FPS drop, even during heavy interactions.

Sampling to control recording volume

You can use built-in sampling rules to record only a percentage of user sessions or target specific session types, such as:

• Sessions with errors

• Premium user journeys

• Certain devices or OS versions

This keeps performance high and storage efficient.

Disable recording for non-production builds

To keep dev/test environments clean, UXCam lets you disable recording in:

• Debug mode

• Staging builds

• Internal QA builds

This ensures that only real user sessions are captured in production, improving data quality while minimizing impact on engineering workflows.

Common Flutter issues solved using session replay

Session replay helps teams diagnose Flutter-specific problems that are hard to catch with logs or analytics. These include;

• Gesture failures: Sometimes taps don’t register due to gesture detector conflicts or invisible overlays.

• Layout overflow issues: On certain device sizes, Flutter widgets overflow or misalign. Session replay reveals exactly where.

• Keyboard UI problems: The keyboard often covers input fields in Flutter apps. Replays show how users struggle with forms.

• Scroll and list issues: Infinite scroll, sticky headers, and custom list views sometimes behave incorrectly.

• Silent UI freezes: Flutter can freeze due to async operations blocking the UI thread, replays show the moment it happens.

• Onboarding drop-offs: Session replay uncovers why users abandon during multi-step flows.

Best practices for using session replay in Flutter apps

To get the most value from session replay, follow these recommended practices for setup, analysis, and cross-team collaboration.

1. Mask sensitive widgets early

Privacy should be configured from the start. Use UXCam’s widget occlusion to mask any sensitive fields,such as password inputs, payment details, or personal information forms. Masking ensures that protected data never appears in session replays, keeping recordings safe, compliant, and suitable for team-wide review.

2. Track key events for context

Session replay becomes far more meaningful when paired with event data. By tracking interactions like button taps, form submissions, feature usage, and error states, you give your team the context needed to understand why users behave the way they do. Combining replays with event metadata makes it easier to verify feature adoption, troubleshoot failed actions, and validate design decisions.

3. Use funnels to diagnose drop-offs

Funnels reveal where users abandon important workflows such as onboarding, checkout, or sign-ups. When you connect these funnels to session replays, you can jump directly into real sessions where drop-offs happen. This combination helps you understand the exact friction points users encounter and why they fail to complete certain tasks, allowing for precise UX improvements.

4. Review sessions from different device types

Flutter apps often behave differently across devices with varying screen sizes, processing power, and refresh rates. Watching replays from small screens, tablets, low-end devices, and high-refresh displays helps you identify layout issues, rendering anomalies, or performance slowdowns that you won’t see in controlled internal testing environments. This ensures your app works smoothly for your entire user base, not just the devices used during QA.

5. Involve product, design, and QA teams

Session replay is most effective when used across teams, not just engineering. Product managers can validate whether new features work as intended. Designers can observe real-world usability and interaction patterns. QA can pinpoint bugs faster by watching replays instead of reproducing complex steps. When the whole team collaborates around session data, decisions become faster, clearer, and grounded in actual user behavior.
