check out flutter_gdb.<topic_end> |
<topic_start>Build the Android version of the Flutter app in the Terminal |
To generate the needed Android platform dependencies, |
run the flutter build command.<topic_end> |
<topic_start>Start debugging with VS Code first |
If you use VS Code to debug most of your code, start with this section.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> |

Click the Attach debugger to Android process button. |
()lightbulb Tip |
If this button doesn’t appear in the Projects menu bar, verify that |
you opened Flutter application project but not a Flutter plugin.The process dialog displays one entry for each connected device. |
Select show all processes to display available processes for each |
device.Choose the process to which you want to attach. |
For this guide, select the com.example.my_app process |

io.flutter plugins.Double click GeneratedProjectRegistrant to open the |
Java code in the Edit pane.At the end of this procedure, both the Dart and Android debuggers interact |
with the same process. |
Use either, or both, to set breakpoints, examine stack, resume execution |
and the like. In other words, debug!<topic_end> |

Go to the toolbar, open the leftmost dropdown menu, and click on |
Open Android Emulator: <device>.You can choose any installed emulator that’s doesn’t include arm64.From that same menu, select the virtual Android device.From the toolbar, click Run ‘main.dart’.You can also press Ctrl + Shift + R.After the app displays in the emulator, continue to the next step.Click the Attach debugge... |

Debug Dart and iOS code using Xcode |
To debug iOS code, you need a Flutter app that contains iOS 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 iOS version of the Flutter app in the Terminal |
To generate the needed iOS platform dependencies, |
run the flutter build command.<topic_end> |

<topic_start>Start the Xcode debugger |
Open ios/Runner.xcworkspace from your Flutter app directory.Select the correct device using the Scheme menu in the toolbar.If you have no preference, choose iPhone Pro 14.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> |
