duplicate_shown_name
Duplicate shown name.
Description
#The analyzer produces this diagnostic when a name occurs multiple times in a show
clause. Repeating the name is unnecessary.
Example
#The following code produces this diagnostic because the name min
is shown more than once:
dart
import 'dart:math' show min, min;
var x = min(2, min(0, 1));
Common fixes
#If the name was mistyped in one or more places, then correct the mistyped names:
dart
import 'dart:math' show max, min;
var x = max(2, min(0, 1));
If the name wasn't mistyped, then remove the unnecessary name from the list:
dart
import 'dart:math' show min;
var x = min(2, min(0, 1));
