[file_selector_linux]When compiling the project with Debian 10, the following error occurred: [-Werror, -Wunused-function] #158900
Description
Steps to reproduce
I attempted to compile the localsend project on Debian 10 using Flutter version 3.24.4, and the error can be replicated on any clean Debian 10 installation.
The basic compilation process is as follows:
apt-get install -y clang cmake libgtk-3-dev ninja-build libayatana-appindicator3-dev libfuse2
git clone -b 3.24.4 https://github.com/flutter/flutter
export PATH=.....
flutter doctor
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
git clone https://github.com/localsend/localsend
cd localsend/app
flutter pub get
flutter pub run build_runner build -d
flutter build linux
Expected results
I tried to compile the localsend project and required glibc to be less than 2.28, so I used the Debian 10 environment. In the earlier versions of this project, compilation was normal.
Actual results
Based on my experience with C language compilation, the error should just be a warning level issue, but when I tried to add the CFLAGS parameter in several CMakeLists files without effect, including the system environment variables.
I'm not sure how to correct this seemingly simple compilation problem. Even I'm not sure if it's a Flutter issue or a problem with the plugin.
