Debug Dart and macOS code using Xcode |
To debug macOS code, you need a Flutter app that contains macOS code. |
In this section, you learn to connect two debuggers to your app: |
Flutter via VS Code and Xcode. You need to run both VS Code and Xcode.These section uses the same example Flutter url_launcher app created |
in Update test Flutter app.<topic_end> |
<topic_start>Build the macOS version of the Flutter app in the Terminal |
To generate the needed macOS platform dependencies, |
run the flutter build command.<topic_end> |
<topic_start>Start debugging with VS Code first |

<topic_start>Start the debugger in VS Code |
To open the Flutter app directory, go to |
File > |
Open Folder… and choose the my_app directory.Open the lib/main.dart file.If you can build an app for more than one device, |
you must select the device first.Go to |
View > |
Command Palette…You can also press Ctrl / Cmd + |
Shift + P.Type flutter select.Click the Flutter: Select Device command.Choose your target device.Click the debug icon |
(). |
This opens the Debug pane and launches the app. |
Wait for the app to launch on the device and for the debug pane to |
indicate Connected. |
The debugger takes longer to launch the first time. |
Subsequent launches start faster.This Flutter app contains two buttons:<topic_end> |
<topic_start>Attach to the Flutter process in Xcode |
To attach to the Flutter app, go to |
Debug > |

Runner.Runner should be at the top of the Attach to Process menu |
under the Likely Targets heading.<topic_end> |

<topic_start>Start the debugger in Xcode |
Open macos/Runner.xcworkspace from your Flutter app directory.Run this Runner as a normal app in Xcode.When the run completes, the Debug area at the bottom of Xcode displays |
a message with the Dart VM service URI. It resembles the following response:Copy the Dart VM service URI.<topic_end> |
