| 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. |
