unused_local_variable
The value of the local variable '{0}' isn't used.
Description
#The analyzer produces this diagnostic when a local variable is declared but never read, even if it's written in one or more places.
Example
#The following code produces this diagnostic because the value of count
is never read:
dart
void main() {
int count = 0;
}
Common fixes
#If the variable isn't needed, then remove it.
If the variable was intended to be used, then add the missing code.
