未在flutter中为类'TextTheme'定义getter'bodyText2'

Question

当我在flutter项目中导入flutter_linkify/flutter_linkify.dart程序包时，在控制台中出现此错误：

Launching lib\main.dart on CRO U00 in debug mode...
Running Gradle task 'assembleDebug'...

Compiler message:

当我在flutter项目中导入任何包时，我会遇到这种错误。我最近更新了我的Android Studio和插件。

Answer 1

textTheme.bodyText2在较新版本的flutter中可用（您使用的是1.12.13 + hotfix.9，它是较旧的版本）。

您有两个选择：

1. 使用旧版本的插件，您的情况是flutter_linkify 3.1.2。

2. 将Flutter升级到较新的版本
