+## Errors while building the example app
+
+### Error Scenario:
+
+When running the following command:
+```
+flutter build linux --release
+```
+You may encounter the following error:
+
+```
+[   +1 ms] /snap/flutter/current/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/11/liblto_plugin.so: error loading plugin:
+/snap/flutter/149/usr/bin/../../lib/x86_64-linux-gnu/libc.so.6: version GLIBC_2.33' not found (required by
+/usr/lib/gcc/x86_64-linux-gnu/11/liblto_plugin.so)
+[        ] collect2: error: ld returned 1 exit status
+[  +96 ms] [3/7] Linking CXX shared library plugins/flutter_
+```
+### Root Cause:
+
+This is caused by a mismatch between the GLIBC version bundled inside the Flutter Snap (e.g. 2.31) and the system‑installed GLIBC version (e.g. GLIBC 2.33+ on Ubuntu 22.04 or Fedora). When the Flutter Snap’s internal linker attempts to load external system libraries, it expects symbols like GLIBC_2.33 or newer—but the libc inside the Snap is only version 2.31—resulting in a conflict
+
+ - The Flutter Snap includes its own GLIBC (version 2.31).
+ - The system is using a modern GLIBC version (e.g. GLIBC 2.33 or newer), as found in current releases such as Ubuntu 22.04 LTS (which ships with GLIBC 2.35)
+ - When LTO (link‑time optimization) is enabled, the internal linker inside the Flutter Snap attempts to invoke external plugins like liblto_plugin.so. These plugins on modern systems require symbols such as GLIBC_2.33 or newer—but the libc bundled inside the Snap is only version 2.31, causing a version mismatch and ultimately a linker failure.[GitHub](https://github.com/flutter/flutter/issues/137036?utm_source=chatgpt.com)
+
+### Solution:
+
+Remove Snap Flutter and install manually
+1. Remove the Snap version completely:
+   ```
+   sudo snap remove flutter
+   sudo snap remove --purge flutter
+   ```
+2. Install Flutter manually using GitHub:
+    ```
+    git clone https://github.com/flutter/flutter.git -b stable ~/flutter  
+    ```
+3. Add Flutter to your PATH: 
+    ```
+    export PATH="$HOME/flutter/bin:$PATH"
+    ```
+4.  Remove Existing Build Cache and Install Essential Linux Build Tools
+    ```
+    rm -rf build/
+    rm -rf .dart_tool/
+
+    sudo apt update
+    sudo apt install clang cmake ninja-build pkg-config libgtk-3-dev
+    ```
+4. Verify installation
+    ```
+    which flutter
+    flutter --version
+    flutter doctor
+    ```
