unused_shown_name

The name {0} is shown, but isn't used.

Description

#

The analyzer produces this diagnostic when a show combinator includes a name that isn't used within the library. Because it isn't referenced, the name can be removed.

Example

#

The following code produces this diagnostic because the function max isn't used:

dart
import 'dart:math' show min, max;

var x = min(0, 1);

Common fixes

#

Either use the name or remove it:

dart
import 'dart:math' show min;

var x = min(0, 1);
