# For information on the generic Dart part of this file, see the

# The following section is specific to Flutter.
flutter:

  # To add assets to your package, add an assets section, like this:
  # assets:
  #  - images/a_dot_burr.jpeg
  #  - images/a_dot_ham.jpeg
  #
  # For details regarding assets in packages, see
  # https://flutter.io/assets-and-images/#from-packages
  #
  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.io/assets-and-images/#resolution-aware.

  # To add custom fonts to your package, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  # fonts:
  #   - family: Schyler
  #     fonts:
  #       - asset: fonts/Schyler-Regular.ttf
  #       - asset: fonts/Schyler-Italic.ttf
  #         style: italic
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
  #       - asset: fonts/TrajanPro_Bold.ttf
  #         weight: 700

问题是您试图使用反射（省道：镜像），这在颤振中是不可能的，因为：

由于反射使默认情况下所有代码都隐式使用，因此它会干扰树抖动

---

我相信这与

内置值生成器提供的JSON序列化有关。

dart包。

似乎我在一个模型类中导入了错误的库。有一次我搬走了图书馆

import 'package:built_collection/built_collection.dart';

所有测试都通过。

您可以发布颤振单元测试吗？其他细节与该问题无关。你的IDE上有错误消息吗？@MarianoZorrilla我已经用单元测试更新了这个问题。几分钟前它还在工作。所有的测试都通过了，现在它不起作用了。让我们看看是否能找到解决方案。从那时起，有些事情必须改变。您是否添加或更新了软件包？或者可能添加了另一个q中不存在的代码
