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

Klarent vs. traditional QA
Klarent vs Flutter integration tests and the Appium Flutter driver
| Flutter integration tests | Appium Flutter driver | Klarent | |
|---|---|---|---|
| Language required | Dart, using the flutter_test / integration_test packages | Dart, plus a separate Appium driver and toolchain | Describe the flow in plain English. No code |
| Widget-key dependency | Requires widget keys or semantic labels added by the app team | Depends on semantic/accessibility labels exposed to Appium | Visual, intent-based identification - no widget keys required |
| Who maintains the suite | App developers, since tests live in the Flutter codebase | QA plus a dedicated Appium/Flutter-driver maintainer | No coding or scripting background required |
| Cross-platform reuse | One test per platform target, run separately | One driver, but still two suites to keep in sync | One test runs on iOS and Android together |

FAQs
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.
