duplicate_
Details about the 'duplicate_definition' diagnostic produced by the Dart analyzer.
The name '{0}' is already defined.
Description
#The analyzer produces this diagnostic when a name is declared, and there is a previous declaration with the same name in the same scope.
Example
#
The following code produces this diagnostic because the name
x is declared twice:
dart
int x = 0;
int x = 1;
Common fixes
#Choose a different name for one of the declarations.
dart
int x = 0;
int y = 1;
