问题描述

原本我在Mac开发的项目，现在win10运行时报如下错误：

../../../AppData/Local/Pub/Cache/hosted/pub.dev/win32-3.1.4/lib/src/guid.dart:31:9: Error: Type 'UnmodifiableUint8ListView' not found.
final UnmodifiableUint8ListView bytes;
^^^^^^^^^^^^^^^^^^^^^^^^^
../../../AppData/Local/Pub/Cache/hosted/pub.dev/win32-3.1.4/lib/src/guid.dart:31:9: Error: 'UnmodifiableUint8ListView' isn't a type.

^^^^^^^^^^^^^^^^^^^^^^^^^
../../../AppData/Local/Pub/Cache/hosted/pub.dev/win32-3.1.4/lib/src/guid.dart:51:17: Error: Method not found: 'UnmodifiableUint8ListView'.
return Guid(UnmodifiableUint8ListView(guid));
^^^^^^^^^^^^^^^^^^^^^^^^^
../../../AppData/Local/Pub/Cache/hosted/pub.dev/win32-3.1.4/lib/src/guid.dart:55:31: Error: Method not found: 'UnmodifiableUint8ListView'.

AS运行Flutter Doctor正常

问题分析

需要将 win32 软件包版本升级到最新版本，或者运行flutter pub upgrade命令将正在使用的所有依赖项升级到最新版本，最终解决问题。

问题解决

**方案一、**降级Flutter

**方案二、**执行命令，以更新软件包

vbscript 复制代码

flutter pub upgrade win32

//如果 pub upgrade win32 无法正常工作，只需运行以下命令
flutter pub global activate -s git https://github.com/jonataslaw/get_cli

flutter pub cache clean

flutter channel stable

flutter clean && flutter pub get

flutter pub upgrade
