아래의 에러는 http library 설치시 발생하는 에러이고, 간략하게 설명하자면
http 1.1.1 라이브러리 버전 이상은 SDK 버전이 3.2.0 이상, 4.0.0 이하이여야 한다
에러의 내용이다.
[{Project}] flutter pub get --no-example

Error on line 32, column 5 of pubspec.yaml: A dependency may only have one source.

[{Project}] flutter pub get --no-example
Resolving dependencies...
The current Dart SDK version is 3.1.5.
Because {Project} depends on http >=1.1.1 which requires SDK version >=3.2.0 <4.0.0, version solving failed.
You can try the following suggestion to make the pubspec resolve:
* Consider downgrading your constraint on http: flutter pub add http:^1.1.0
exit code 1

당연히 dart sdk 의 버전을 올려주면 문제 해결이 되기때문에 간단한 명령어로 dart sdk 버전을 업그레이드 해준다
flutter upgrade 를 입력해주면 아래와 같이, 업그레이드 작업이 수행된다.
