[플러터(Flutter)] - don't support null safety

플러터 공식문서를 보며 첫 Flutter 앱 작성하기를 따라 하던 중 패키지 적용하는 부분에서 don't support null safety: - package:english_words 가 나타났다.

아래의 두가지 방법 중 하나를 이용하여 해결할 수 있다

 

1. 터미널을 열고 flutter run --no-sound-null-safety를 입력해준다

% flutter run --no-sound-null-safety
Launching lib/main.dart on iPhone 12 Pro Max in debug mode...
Running Xcode build...                                                  
 └─Compiling, linking and signing...                      1,515ms
Xcode build done.                                           14.3s
Syncing files to device iPhone 12 Pro Max...                        73ms

Flutter run key commands.
r Hot reload. 🔥🔥🔥
R Hot restart.
h Repeat this help message.
d Detach (terminate "flutter run" but leave application running).
c Clear the screen
q Quit (terminate the application on the device).
