VS Code (OSX) Flutter hot reload is not triggered by save

Question

After upgrading VS Code version to 1.32.1 automatic hot reloading is not triggered by saving / auto saving. It worked like a charm before.

Hot reloading still works by pressing hot reload button.

According to Flutter doctor Flutter seems OK:

Doctor summary (to see all details, run flutter doctor -v):

[✓] Flutter (Channel beta, v1.2.1, on Mac OS X 10.14.2 18C54, locale hu-HU)

[✓] Android toolchain - develop for Android devices (Android SDK version 28.0.3)

[✓] iOS toolchain - develop for iOS devices (Xcode 10.1)

[✓] Android Studio (version 3.2)

[✓] VS Code (version 1.32.1)

[✓] Connected device (2 available)

Do you have the same experiences? Do you have any suggestions to solve it?

Answer 1

I had the same problem. Currently I am using VSCode version 1.39.2.

For the hot reload to work you need to start debugging in VSCode.

As it says in the docs: "Only Flutter apps in debug mode can be hot reloaded." https://flutter.dev/docs/development/tools/hot-reload

You can find that option on the VSCode's top navigation inside Debug or with the shortcut F5.

You don't need to do flutter run on your terminal, nor even on VSCode, is just start debugging and it will launch lib/main.dart in debug mode.

If that doesn't solve the problem, try downgrading to the last version of VSCode.

Edit: This issue has been fixed in VS Code 1.32.2 which is now live. No, it's not fixed in 1.32.2!

it dosn't work at all for me. I don't see neither loading icon, nor hot-reloaded changes
