mixin_instantiate

Details about the 'mixin_instantiate' diagnostic produced by the Dart analyzer.

Mixins can't be instantiated.

Description

#

The analyzer produces this diagnostic when a mixin is instantiated.

Example

#

The following code produces this diagnostic because the mixin M is being instantiated:

dart 
mixin M {}
​
var m = M();

Common fixes

#

If you intend to use an instance of a class, then use the name of that class in place of the name of the mixin.

Unless stated otherwise, the documentation on this site reflects Dart 3.13.0. Report an issue.
