How can I suppress specific flycheck messages in sh-mode?

Question

In sh-mode I am getting following flycheck-error message:

File Line [v]ColLevel ID Message (Checker) config.sh 2 error Syntax error: "(" unexpected (sh-posix-dash)

for the following line: strings=("hello" "world") . But this is actually a valid expression in bash.

complete file:

#!/bin/bash strings=("hello" "world")

init.el file has following lines, reference:

(define-derived-mode my-cfg-mode sh-mode "My CFg Mode" "A mode for my CFg files." (sh-set-shell "bash"))

Is it possible to suppress this warning message?

Can't reproduce it: flycheck is happy with it. What does the complete file look like? Is there a shebang on line 1? And what is sh-posix-dash? — NickD

@NickD sh-posix-dash is one of the shell checkers in flycheck — nega

@NickD Yes sir there is #!/bin/bash line (updated on my question). flycheck-sh-posix-dash-executable is set to nil — alper

As checker sh-posix-dash was enabled. When I add following lines into my init.el file the problem is solved.

(with-eval-after-load 'flycheck (setq-default flycheck-disabled-checkers '(sh-posix-dash)))

As @Ian mention core cause was due to following lines, hence also removing those lines from my init.el file was also resolved the conflict:

(define-derived-mode my-cfg-mode sh-mode "My CFg Mode" "A mode for my CFg files." (sh-set-shell "bash"))
