## ◆ fl_platform_plugin_request_app_exit()

void fl_platform_plugin_request_app_exit | ( | FlPlatformPlugin * | plugin | ) |

fl_platform_plugin_request_app_exit: @plugin: an #FlPlatformPlugin

Request the application exits (i.e. due to the window being requested to be closed).

Calling this will only send an exit request to the framework if the framework has already indicated that it is ready to receive requests by sending a "System.initializationComplete" method call on the platform channel. Calls before initialization is complete will result in an immediate exit.
