When building a snap of a flutter linux app using desktop_drop plugin, the build fails with an error:

/root/parts/desktop-drop-example/build/linux/flutter/ephemeral/.plugin_symlinks/desktop_drop/linux/desktop_drop_plugin.cc:69:29: error: no member named 'getenv' in namespace 'std'; did you mean simply 'getenv'?

This does not happen when building using flutter build linux

Reproduce Steps

Steps to reproduce the behavior:

1. Copy the sample snapcraft.yaml file into the snap/ directory at the root of the plugin's example app
2. Install snapcraft and other things mentioned here: https://docs.flutter.dev/deployment/linux
3. Run snapcraft --use-lxd
4. See compilation error about desktop_drop_plugin.cc

Expected behavior

snapcraft --use-lxd should build without any compilation errors same as flutter build linux
