请问什么时候出flutter 3.0的包

readme中说支持Flutter SDK 2.10.0, 2.10.1, 2.10.2, 2.10.3;
但是我看merge已经合并了相关3.0的支持？

How does fair compare to dynamic_widget?

Thanks for creating the flutter package.

As fair is relative new compare to dynamic_widget at https://pub.dev/packages/dynamic_widget, may I know why you guys created fair instead of reuse the implementation of dynamic_widget?

不支持多个delegate

问题
目前delegate名称必须与fairwidget名称对应，不能支持多个delegate。
fairplugin不支持dart到js的自动转化，每次需要手写js。

预期
可以支持一个fairwidget支持多个delegate。
fairplugin支持dart到js的自动转化。

dart2dsl和json_serializable冲突

dart2dsl中AstNodeMapBuilder没有指定generatedExtension，导致与json_serializable冲突出错。
报错：Both fair_dart2dsl:ast_node_map_builder and source_gen:combining_builder may output test/widget_test.g.dart. Potential outputs must be unique across all builders. See https://github.com/dart-lang/build/blob/master/docs/faq.md#why-do-builders-need-unique-outputs。

项目中引入 Fair 后，构建出 Release 包，安装后启动 APP 直接闪退

问题

为什么会这样。。

windows 环境下 log 文件名包含非法字符

执行 flutter pub run build_runner build 编译失败时无法输出日志，因为 windows 下的文件名不允许包含冒号。

FileSystemException: Cannot create file, path = 'build\fair\log\2021-03-20_10:58:048.txt' (OS Error: 文件名、目录名或卷标语法不正确。, errno = 123)

flutter pub run build_runner build 报错

flutter版本 2.5.0
使用 flutter pub run build_runner build 转换报错

如果有一个类似FlutterFlow那个可视化的工具来生成bundle那就更棒了

autoImport

autoImport 可执行文件是什么内容？

部分组件布局时候转换报错，函数参数传递怎么实现

环境：flutter 2.0.6版本 macos 12.0.1
问题：1.很多组件映射不成功，提示没有注册的type类型吗？2.build函数中的布局，提取出去函数但是带有参数传递怎么写？
例如，
1、InkWell is not register
2、ElevateButton is not register
3、type 'WarningWidget' is not a subtype of type is not a subtype of type ‘inputDecoration’
4、The following _TypeError was thrown while parsing widget of ListView.builder,
Closure: (dynamic) =>
ListView:
type '([dynamic]) => dynamic' is not a subtype of type '(BuildContext, int) =>
Widget'
