| |
| If you have found a performance problem, then fill out the template below. |
| Please read our guide to filing a bug first: https://flutter.dev/docs/resources/bug-reports |
| --> |
| |
| ## Details |
| |
| <!-- |
| 1. Please tell us exactly how to reproduce the problem you are running into, and how you measured the performance. |
| |
| 2. Please attach a small application (ideally just one main.dart file) that |
| reproduces the problem. You could use https://gist.github.com/ for this. |
| |
| 3. Switch flutter to master channel and run this app on a physical device |
| using profile or release mode. Verify that the performance issue can be |
| reproduced there. |
| |
| The bleeding edge master channel is encouraged here because Flutter is |
| constantly fixing bugs and improving its performance. Your problem in an |
| older Flutter version may have already been solved in the master channel. |
| --> |
| |
| <!-- |
| Please tell us which target platform(s) the problem occurs (Android / iOS / Web / macOS / Linux / Windows) |
| Which target OS version, for Web, browser, is the test system running? |
| Does the problem occur on an emulator/simulator as well as on physical devices? |
