Flutter.h未找到问题Flutter 2
Flutter.h未找到问题Flutter 2
提问于 2021-11-20 22:31:06
我遇到了这个问题，应用程序没有构建，因为它说
fatal error: 'Flutter/Flutter.h'
file not found
#import <Flutter/Flutter.h>我已经在这个问题上工作了一整天，但没有任何进展。这是一个简单的程序(打开flutter新项目时获得的初始代码)，并且添加了firebase_core。
整个XCode输出：
Xcode's output:
↳
In file included from
/Users/alfieanil/Developer/flutter/.pub-cache/hosted/pub.dartlang.org/firebase_cor

任何帮助都是非常感谢的。
谢谢

我通过以下步骤设法解决了这个问题：
1. Open your terminal in root level of your project.
2. run flutter upgrade.
3. Change SDK version in pubspec.yaml file
4. In my pubspec.yaml I just changed This line sdk: “>=2.7.0 <3.0.0” and replaced with sdk: “>=2.12.0 <3.0.0”
5. flutter clean
6. flutter run.原始链接：https://fluttercorner.com/error-null-safety-features-are-disabled-for-this-library/ (方案1)
