Flutter 3.7.12 Linux平台非空安全运行异常求助

问题链接 #

https://github.com/flutter/flutter/issues/136791

复现步骤 #

• 在Linux系统上安装并配置Flutter 3.7.12
• 执行命令：flutter build linux --release --no-sound-null-safety 或 flutter run -d linux --no-sound-null-safety

实际运行情况 #

• 基于Flutter 1.2开发的商业项目，多处未适配空安全特性，在Windows平台使用Flutter 3.7.12并添加@dart=2.9注解后可正常运行所有功能
• 在X86架构Linux系统上配置相同版本Flutter 3.7.12后，项目能启动但因空检查异常导致大量功能无法使用
• 因时间限制无法全面适配代码至空安全，且官方说明Flutter 3.7.12是最后支持非空安全的版本，希望找到无需修改代码即可在Linux平台正常运行的解决方案
