Top Flutter Performance and Crash Insights packages
Last updated: January 26, 2025
App performance analysis deals with the analysis of application performance data. To measure the performance of a Flutter app, you can use a variety of tools. One popular tool is the Dart Devtools, which allows you to measure the performance of your app on a variety of devices. Another tool you can use is the Android Studio profiler, which provides you with a detailed view of your app's performance. Various Flutter packages also provide tools to directly view the app performance while running on a device.
In production apps, it is also important to identify any issues that led to a crash while operating an app. This process is known as Crash analytics where data related to app crashes are collected, analyzed and reported. It is typically used to improve app quality by identifying and fixing defects that cause crashes. Crash analytics can also be used to troubleshoot customer issues and track the root cause of crashes. Firebase Crashalytics and Sentry are two popular Crash Analytics & Insights tools.
