Flutter app testing

Flutter app testing on iOS and Android

Flutter draws its own UI, so standard locators have little to grip. Klarent identifies widgets the way a user sees them and runs one test across both platforms.

The Flutter testing problem

Why Flutter apps are hard to automate

A canvas, not a UI tree

Flutter renders to a canvas, so the widget tree is opaque to conventional element locators.

Dart-only tooling

Flutter integration tests live in Dart, so QA cannot own them without Dart skills.

A second toolchain

The Appium Flutter driver adds a second toolchain to install, configure and maintain.

Platform-specific behavior

The same Flutter UI can behave differently across iOS and Android, creating platform-specific test cases.

Brittle test maintenance

UI changes, widget refactors and key updates can break automation even when the user flow still works.

Platform

Everything your mobile QA team needs

From generating your first test to keeping it green after every app update. Klarent handles every step.

Platform capabilities

Built for how Flutter app testing actually works

One test, both platforms

Run a single Flutter test across iOS and Android from the same codebase.

Self-healing locators

Locators adapt automatically through Flutter SDK upgrades and layout changes.

Material and Cupertino support

Material and Cupertino variants of the same screen are handled in one flow.

Run evidence on every failure

Every failure ships with video, logs, screenshots and the exact failing step.

Test coverage

What you can test in a Flutter app

Authentication

Onboarding, authentication and biometric flows.

Custom-painted and animated widgets

Custom-painted and animated widgets that standard locators miss.

Gestures and scrolling

Scrolling lists, gestures, swipes and drag interactions.

Platform channel calls

Camera, storage and permission requests routed through platform channels.

Notifications and deep links

Push notifications and deep links.

Network and offline states

Offline mode, slow connections, network interruptions and recovery flows.

Klarent vs Flutter integration tests and the Appium Flutter driver

Run your Flutter build through Klarent.

Upload your Flutter iOS and Android builds (or connect your CI pipeline), describe the flow in plain English, and Klarent identifies widgets visually - the way a user sees them - rather than relying on widget keys. One test runs on both platforms and reports back with full run evidence.

No. Klarent identifies widgets visually and by intent, so your app team does not need to add or maintain widget keys or semantic labels for automation to work.

No. Klarent tests are described in plain English, not Dart. There is no Flutter integration test code for QA to own or maintain.

Flutter integration tests live in Dart and are typically written and owned by app developers. Klarent tests are authored in plain English, identify widgets visually instead of by key, and self-heal automatically when the app changes.

You do not need it. Klarent replaces the Appium Flutter driver entirely, so there is no second toolchain to install, configure or maintain alongside your test suite.

Klarent supports current and recent stable Flutter SDK releases, and self-healing locators keep tests passing through SDK upgrades.

Yes. Klarent runs a single Flutter test across iOS and Android from the same codebase, and reports results per platform.

Klarent identifies custom-painted and animated widgets the way a user would - visually and by intent - so flows that standard element locators miss are still testable.
