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. labels: 'from: performance template' body: - type: markdown attributes: value: | Thank you for using Flutter! If you are looking for support, please check out our documentation or consider asking a question on Stack Overflow: - https://flutter.dev/ - https://api.flutter.dev/ - https://stackoverflow.com/questions/tagged/flutter?sort=frequent - type: textarea attributes: label: Steps to reproduce description: Please tell us exactly how to reproduce the problem you are running into, and how you measured the performance. placeholder: | 1. ... 2. ... 3. ... validations: required: true - type: textarea attributes: label: Code sample description: | 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. value: |
