unnecessary_non_null_assertion

The '!' will have no effect because the receiver can't be null.

Description

#

The analyzer produces this diagnostic when the operand of the ! operator can't be null.

Example

#

The following code produces this diagnostic because x can't be null:

dart
int f(int x) {
  return x!;
}

Common fixes

#

Remove the null check operator (!):

dart
int f(int x) {
  return x;
}
