플러터 -Dart 정규표현식

서버로 여러가지 post request api를 날릴때
이모지를 제거 하기로 했다. 😀

 

텍스트 필드에서 애초에 필터링 하도록 만들기로 합의했다.

 

여하튼 그래서 내가 쓴 관련 정규식을 정리한다.

 

ps. 앱내에 다른곳에서 한영숫자만 허용하는 부분도 있기 때문에 분리하였다.

 

[  한글(모음자음포함), 영어(대소문포함), 숫자, 특수문자일부 ]

1. 한영숫자공백허용

  static RegExp basicReg = RegExp(r"^[ㄱ-ㅎ가-힣0-9a-zA-Z\s+]*$");

 

2. 특수문자 일부

  static RegExp specialChar = RegExp(r'''
  ^!#%&@`:;-.<>,~\\(\\)\\{\\}\\^\\[\\][*][+][$][|][']["]
  ''');

3. 이모지ㅇ

Static RegExp emoji = RegExp(
