Fedora 36上Flutter运行报错：无法加载swrast驱动

执行flutter run后页面空白，调试控制台输出如下错误：

解决方法 #

问题根源是Snap版本Flutter自带的系统库与Fedora 36的系统库存在版本冲突，以下是可行的解决途径：

1. 替换为官方手动安装版Flutter #

• 卸载Snap版Flutter：

  sudo snap remove flutter
  

• 从Flutter官方渠道下载对应版本的压缩包，解压到本地目录（如~/flutter）
• 将Flutter的bin目录加入系统PATH：
  在~/.bashrc或~/.zshrc中添加：

  export PATH="$PATH:$HOME/flutter/bin"
  

• 执行source ~/.bashrc（或对应shell的配置文件）使设置生效
• 重新运行flutter doctor检查环境，之后再尝试flutter run

2. 临时指定系统库优先级运行 #

若不想卸载Snap版，可在运行时强制使用系统库：

LD_LIBRARY_PATH=/lib64 flutter run

此命令临时让系统/lib64目录下的库优先加载，规避Snap自带库的冲突问题。

3. 安装32位依赖库（可选） #

部分场景下32位库缺失会触发类似错误，执行以下命令安装：

sudo dnf install mesa-libGL.i686 mesa-libGLU.i686
