问题描述

将Flutter SDK更新到3.7.9后，运行项目出来以下错误提示。

Could not build the precompiled application for the device.
Error (Xcode): ../../../.pub-cache/hosted/pub.flutter-io.cn/file-6.1.2/lib/src/interface/file.dart:15:16: Error: The method 'File.create' has fewer named arguments than those of overridden method 'File.create'.


Error launching application on iPhone.

解决方案

根据错误提示，是某个库依赖了google的file库的6.1.2版本，File.create方法需要几个参数。
我们进入pub中查看file的更新信息。
file|dart package:https://pub.flutter-io.cn/packages/file/changelog
file库版本更新日志
可以看到，从6.1.3开始，create方法增加了一个bool类型的参数，所以我们只需要将file库的版本升级到6.1.3以上即可。

项目中覆盖库版本

最粗暴的方式是直接在项目的pubspec.yaml中指定file库的版本，这样编译时会统一库的版本。

# The following line prevents the package from being accidentally published to

publish_to: 'none' # Remove this line if you wish to publish to pub.dev

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
