I figured out how to disable screen capture in Flutter Windows Application
API Reference: https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-setwindowdisplayaffinity
Navigate to Project/windows/runner/main.cpp
Add the below code in wWinMain method:
//DISABLE SCREEN
HWND code =window.GetHandle();
SetWindowDisplayAffinity(code, 0x00000011);
main.cpp:
#include <flutter/dart_project.h>
#include <flutter/flutter_view_controller.h>
#include <windows.h>
#include "flutter_window.h"
#include "utils.h"
int APIENTRY wWinMain(_In_ HINSTANCE instance, _In_opt_ HINSTANCE prev,
_In_ wchar_t *command_line, _In_ int show_command) {
// Attach to console when present (e.g., 'flutter run') or create a
// new console when running with a debugger.
if (!::AttachConsole(ATTACH_PARENT_PROCESS) && ::IsDebuggerPresent()) {
CreateAndAttachConsole();
}
// Initialize COM, so that it is available for use in the library and/or
// plugins.
::CoInitializeEx(nullptr, COINIT_APARTMENTTHREADED);
flutter::DartProject project(L"data");
std::vector<std::string> command_line_arguments =
GetCommandLineArguments();
project.set_dart_entrypoint_arguments(std::move(command_line_arguments));
FlutterWindow window(project);
Win32Window::Point origin(10, 10);
Win32Window::Size size(1280, 720);
if (!window.CreateAndShow(L"windows_app", origin, size)) {
return EXIT_FAILURE;
}
//DISABLE SCREEN
HWND code =window.GetHandle();
SetWindowDisplayAffinity(code, 0x00000011);
window.SetQuitOnClose(true);
::MSG msg;
while (::GetMessage(&msg, nullptr, 0, 0)) {
::TranslateMessage(&msg);
::DispatchMessage(&msg);
}
::CoUninitialize();
return EXIT_SUCCESS;
