MetaTags and Attributes-
Meta tags
Meta tags are HTML tags used to provide additional information about a page to search engines and other clients. Clients process the meta tags and ignore those they don't support. Meta tags are added to the <head> section of your HTML page and generally look like this:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="description" content="Author: A.N. Author, Illustrator: P. Picture, Category: Books, Price: £9.24, Length: 784 pages">
<meta name="google-site-verification" content="+nxGUDJ4QpAZ5l9Bsjdi102tLVC21AIh5d1Nl23908vVuFHs34=">

Google Search supports a limited number of HTML attributes for indexing purposes. Attributes like src and href are used for discovering resources such as images and URLs.

However, some parts of the interface require the same code snippets across multiple routes — for example, the navigation header, footer, and sidebar. To manage this, we use layouts to structure the interface in a way that contains shared code snippets. Next.js recommends starting a new project with the App Router. However, we’ll discuss how to implement layouts and nested layouts with the Pages Router for users who have yet to migrate to the new Next.js routing system.
How to Parse JSON in Dart/Flutter Parsing JSON is a very common task for apps that need to fetch data from the Internet. And depending on how much JSON data you need to process, you have two options: write all the JSON parsing code manually automate the process with code generation Encoding and Decoding JSON When a JSON response is sent over the network, the entire payload is encoded as a string. But inside our Flutter apps, we don't want to extract the data from a string manually:
