Bug Causing Dart.exe to Eat Up All Available Memory.

[aalharbi169638]

There's a reproducible bug that causes dart.exe to take up all available RAM in my device; I was able to reproduce this bug multiple times. I couldn't find any good solution online though.

the only packaged I used for this project is the http package published by dart.dev.

The issue occurs exactly when i type "http.Response response = http.g" inside the Future method to use the get method for that package.

Thank you,

Summary: The user is experiencing a memory leak in dart.exe when using the http package's get method within a Future function. This issue consistently occurs when attempting to assign the result of http.get to a http.Response variable.

Analyzer eating through all available memory should not be P2. Can somebody look at this?
