Can't specify a nested list type with @Default()

[Reprevise]

Describe the bug
When specifying a nested list type using @Default() like so: @Default(<List<dynamic>>[]), the generated code errors. If you use @Default(<List>[]) instead, it works fine.

Error details

[SEVERE] freezed on lib/example.dart:
An error `FormatterException` occurred while formatting the generated source for
`package:small_dart/example.dart`
which was output to
`lib/example.freezed.dart`.
This may indicate an issue in the generator, the input source code, or in the
source formatter.
Could not format because the source could not be parsed:

To Reproduce

Run build_runner on the class below:

import 'package:freezed_annotation/freezed_annotation.dart';

part 'example.freezed.dart';

@freezed
class ExampleClass with _$ExampleClass {
  const factory ExampleClass({
    @Default(<List<dynamic>>[]) List<List<dynamic>> data,
  }) = _ExampleClass;
}

Expected behavior
The build_runner process should've completed successfully and the generated code should be correct with no errors.

A workaround would be:

const _dataDefault = <List<dynamic>>[];

@freezed
class ExampleClass with _$ExampleClass {
  const factory ExampleClass({
    @Default(_dataDefault) List<List<dynamic>> data,
  }) = _ExampleClass;
}
