Flutter: Catch Your First Crash in Under 10 Minutes

Overview

With the AppAmbit SDK already installed in a Flutter app, this is the other half of activation: catch a real crash, and read it in one place instead of digging through device logs. By the end, you'll have forced a crash and pulled its full report from the dashboard — in under ten minutes.

What You'll Learn

• How AppAmbit's Flutter SDK captures crashes automatically once initialized
• Forcing a real, uncaught crash for testing
• Where the crash report shows up in the dashboard
• Reading the stack trace, device, and session data behind it

Prerequisites

Before you begin, make sure you have:

1. A Flutter app with the AppAmbit SDK (appambit_sdk_flutter) already installed and initialized (SDK setup guide if you haven't yet — this video doesn't cover installation)
2. An AppAmbit account (sign up for free)
3. The app running on a device or simulator

Crash Reporting Is Already On

Once AppambitSdk.start(appKey: 'YOUR-APP-KEY') runs in main.dart, AppAmbit is already watching for uncaught crashes — there's nothing extra to wire up. To see the flow end-to-end, we force one on purpose.

Trigger a Test Crash

Add a temporary button to test the crash function:

ElevatedButton(
  onPressed: () {
    AppAmbitSdk.generateTestCrash();
  },
  child: const Text('Throw Crash'),
)

This code is for testing only. Remove it before release.

Tap the button. The app terminates. Reopen it — this is what delivers the crash report to AppAmbit on the next launch.

Verify the Crash Report

Back in AppAmbit, open Diagnostics. The report may take a few seconds to arrive — refresh if necessary. Once processed, the crash appears in the chart and the diagnostics list.

Open it to see unique users, app versions, occurrence count, and when it was last seen, plus the full stack trace pointing at the line that threw. Further down, the device, OS, and app version behind the crash, plus By OS and By Device breakdowns.
