> 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.
