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);
