Flutter 在“颤动医生”期间崩溃

Question

My setup

• macOS Mojave
• Xcode 10.3
• Android Studio 3.5 with latest SDK and NDK.

I recently upgraded flutter from 1.7.8 to 1.9.1+hotfix, but the immediate flutter doctor -v crashes in the middle, giving this Terminal output.

$ flutter doctor -v
[✓] Flutter (Channel stable, v1.9.1+hotfix.2, on Mac OS X 10.14.6 18G95, locale en-CA)
    • Flutter version 1.9.1+hotfix.2 at /Applications/Android/flutter
    • Framework revision 2d2a1ffec9 (8 days ago), 2019-09-06 18:39:49 -0700
    • Engine revision b863200c37
    • Dart version 2.5.0

⣽Unhandled exception:

Did anyone see this?

Answer 1

First run: flutter config --clear-features

then flutter config --no-analytics and flutter update-packages

if all goes like ok, you can run flutter doctor nicely.

Answer 2

Firstly, you should always run the flutter command to avoid returning errors when you run the flutter doctor command. had the same issue and when i did this it worked perfectly.
