CrashOps Plugin for Flutter #

License: MIT

This Flutter plugin helps to bridge with the CrashOps native SDK. CrashOps SDK helps you monitor your Flutter app's native crashes (we will add support for Flutter errors as well in the future versions).

Installation #

Easiest to install, it's a plug n' play plugin. All you need to do is add this dependency ("crashops_flutter") and the SDK will automatically start monitoring after each application launch.

Install by adding crashops to your pubspec.yaml file, for example:

    sdk: flutter
  crashops: any

Usage #

<TODO: Add informative instructions>

Don't have Flutter yet? #

plug-in package, a specialized package that includes platform-specific implementation code for Android and/or iOS.

For help getting started with Flutter, view our online documentation, which offers tutorials, samples, guidance on mobile development, and a full API reference.


Go live :)

Our SDK is still under development, stay tuned:

0.0.1 #

  • First version ever - it's a plug n' play plugin that initiates our native SDK, it will simply wait for app crash and report on next app lunch. The client ID may be supplied via code or the config file (for more info see our docs).

0.0.2 #

  • Renamed: "crashops_flutter" => "crashops". Added plain test.

0.0.3 #

  • Improving plugin by following "" analysis recommendations
