After importing the Dart developer package, you can access a large number of cool debugging, performance profiling and tracing tools, including PostEvent.

The improvements of these tools are aimed at improving your development efficiency and making it easier for you to find out when a particular widget was built.

Flutter application examples

We are also continuing to update, so that you can use more Google APIs and related services in Flutter and Dart applications. One example is the official launch of Dart on Google Cloud Run, which can containerize Dart applications with a small amount of code, and then obtain smaller binary files that can be run on the backend.

We also cooperated with Firebase to launch the I/O photo booth , and provided the source code and corresponding codelab. Welcome everyone to get started.
