React Native Animated ProgressBar

React Native is an open-source UI software framework created by Meta Platforms, Inc. It is used to develop applications for Android, Android TV, iOS, etc. We’re always looking for shorter development cycles, quicker time to deployment, and better app performance.

Syntax:

<ProgressBar
     progress={*}
     height={*}
     backgroundColor="*"
   />

Props in Animated Progress Bar:

height: It is used to set the height of the progress bar.
backgroundColor: It is used to set the color of progressbar.
animated: This prop takes a boolean value for enabling or disabling animation.
indeterminate: It takes a boolean value to Set the bar to animate constantly as loading progress.
progress: It Chooses the point where the progress should animate, based on the progress bar width.
trackColor: which sets the color of the progress bar track.

expo init "projectName"

Step 3: Now go into the created folder and start the server by using the following command.
