+name: My app has some non-speed performance issues
+description: |
+  You are writing an application but have discovered that it uses too much memory,
+  too much energy (e.g., CPU/GPU usage is high), or its app size is too large.

+        Please create a minimal reproducible sample that shows the problem and attach it below between the lines with the backticks.
+
+        Try to reproduce the problem in a test app. Either run `flutter create janktest` and recreate the situation you are experiencing in that app, or clone your app and delete code until you have the jank reproducing with a single `.dart` file.
+
+        If you need more than just a `.dart` file (for example, assets are needed to reproduce the issue, or plugins/packages are needed to reproduce the issue) then create a GitHub repository and upload code there.
+
+        Without this we will unlikely be able to progress on the issue, and because of that we regretfully will have to close it.
+
+        Note: Please do not upload screenshots of text. Instead, use code blocks or the above mentioned ways to upload your code sample.
