unused_local_variable

The value of the local variable '{0}' isn't used.

The analyzer produces this diagnostic when a local variable is declared but never read, even if it's written in one or more places.

The following code produces this diagnostic because the value of count is never read:

void main() {
  int count = 0;
}

If the variable isn't needed, then remove it.

If the variable was intended to be used, then add the missing code.

Unless stated otherwise, the documentation on this site reflects Dart 3.8.0. Page last updated on 2025-05-08. View source or report an issue.
