Unlock SlideBar is a widget that is seen in most Android devices on the lock screen for opening a lock. Along with the lock screen, this type of SlideBar is also seen in many payment apps while making a payment. In this video, we will be creating a simple application for implementing this unlock SlideBar inside our flutter application. For implementing this unlock SlideBar we will be using the slide button library in a flutter. We will be using this library for implementing the sliding button for creating our unlock SlideBar. Inside our application, we will be displaying two screens. In the first screen, we will be simply displaying a unlock SlideBar with a simple TextView as a lock screen. And on sliding the unlock SlideBar we will be opening a new screen that displays a text message as welcome to GeeksforGeeks which will be our home screen. We will be building this application using dart as a programming language. We will be using Android studio as an IDE. This project will surely help beginner or intermediate level Android developers to brush up and enhance their Android development skills.
