我需要帮助将我的 flutter 项目转换为 apk 文件

Question

我已经构建了一个简单的颤振短信报告系统，但我面临着将我的项目转换为 APK 文件格式的挑战。 Flutter 开发人员可以在 2024 年 10 月 7 日之前帮我做到这一点吗？

我已尝试使用 CMD 提示将 flutter 项目转换为 APK 文件，但我认为我的设置存在 gradle 问题，因此无法转换文件。

我尝试过使用CMD方法：

• flutter 构建 apk

• flutter 构建 apk --release

但是在运行命令后，我收到一条错误消息：

Microsoft Windows \[Version 10.0.22631.4249\]

 Building with sound null safety

package:electionresults_results_sms_collation_mobileapp//main.dart: Error: No 'main' method found.

Try adding a method named 'main' to your program.

项目是否构建并运行成功？您似乎有构建错误。日志说找不到 main.dart。确保它位于project_directory/lib/main.dart中。

您还应该在 pubspec.yaml 文件所在的位置运行

flutter build apk

命令。

如果您所做的一切正确但无法解决问题，请尝试运行

flutter clean

，然后再次构建。
