Warns when a local variable is not referenced or is only used as an initializer of another local variable.

Such variables introduce unnecessary complexity and does not affect the meaning of the code.

Example​

❌ Bad:

void fn() {
  var a = 1; // LINT: Avoid unnecessary local variables. Try using the value directly.
  var b = a;
  print(b);

  var c = 2;
  var d = c; // LINT: Avoid unnecessary local variables. Try using the value directly.
  print(c);
}

✅ Good:

void fn() {
  var b = 1;
  print(b);

  var c = 2;
  print(c);
}
