 ## FAQ:
 1. When running the project, an error of Member notfound:'isOhos' is reported: Please ensure that all dart patches are applied in the src/third_party/dart directory (the patches are located in the src/flutter/attachment/repos directory, and you can use git apply to apply the patch). Recompile the engine after patching
-   
+
 2. Prompt Permission denied: Execute chmod +x <script file> to add execution permissions
 
 3. Compile the engine in debug/release/profile mode separately: `./ohos -t debug|release|profile`
 
 4. See help: `./ohos -h`
 
+5. Due to the different ways Windows, macOS, and Linux handle line endings, applying Dart patches can result in different Dart VM snapshot hash values. You can obtain the current snapshot hash value using the following method:
+
+   ```shell
+   python xxx/src/third_party/dart/tools/make_version.py --format='{{SNAPSHOT_HASH}}'
+   ```
+
+   Here, xxx is the engine path you created yourself.
+
+   If the obtained value is not "8af474944053df1f0a3be6e6165fa7cf", then you need to check whether all lines at the end of the xxx/src/third_party/dart/runtime/vm/dart.cc file and the xxx/src/third_party/dart/runtime/vm/image_snapshot.cc file end with LF. On Windows, you can use Notepad++; for other systems, please consult specific methods on your own.

 4. 查看帮助：`./ohos -h`
 
+5. 由于windows和mac、linux对换行符处理方式不同，在应用dart补丁时会造成dart vm snapshot hash结果不同，可通过以下方法获取当前snapshot hash值
+
+   ```shell
+   python xxx/src/third_party/dart/tools/make_version.py --format='{{SNAPSHOT_HASH}}'
+   ```
+
+   其中xxx为创建的engine路径
+
+   如果获取到的值不是“8af474944053df1f0a3be6e6165fa7cf”那么就需要检查xxx/src/third_party/dart/runtime/vm/dart.cc文件和xxx/src/third_party/dart/runtime/vm/image_snapshot.cc文件中全部行的结尾是不是以LF结尾的，windows可以使用notepad++查看，其它系统具体方法请自行查询
