Bắt đầu với reproducer secure-text-entry-flicker được liên kết và chạy nó bằng yarn ios trên trình mô phỏng hoặc thiết bị iOS. Xác minh hiện tượng nhấp nháy khi secureTextEntry sử dụng phông chữ tùy chỉnh và một ký tự được nhập rồi xóa, đồng thời so sánh các renderer mới và cũ; hoàn tất có nghĩa là văn bản không còn nhấp nháy trong cả hai trường hợp.
