Flutter is a popular framework for building high-performance, cross-platform applications, including web applications. However, when building web applications with Flutter, you may encounter a problem where the URL contains a hash symbol (#). This can make the URL difficult to read and can also cause problems with SEO. Fortunately, there is a way to remove the hash symbol from the URL in Flutter web applications.

The hash symbol in the URL is typically used for client-side routing, which allows the application to change the content on the page without reloading the entire page. This is a common technique used in single-page applications, where the user interface is updated dynamically as the user interacts with the application.

To remove the hash symbol from the URL in a Flutter web application, you need to use the HTML5 History API. This API allows you to modify the browser's history without actually loading a new page. Here's how to do it:

Step 1: Import the 'dart:html' package

To use the HTML5 History API in your Flutter web application, you need to import the 'dart:html' package at the top of your main.dart file:

import 'dart:html';

Step 2: Create a function to remove the hash symbol

Next, you need to create a function that will remove the hash symbol from the URL. Here's an example function:

void removeHashFromUrl() { if (window.location.hash.isNotEmpty) { window.history.replaceState(null, '', window.location.href.replaceAll('#', '')); } }

This function checks if the current URL contains a hash symbol, and if it does, it uses the 'replaceState' method to modify the URL and remove the hash symbol.

Step 3: Call the function on page load

Finally, you need to call the 'removeHashFromUrl' function when the page loads. You can do this by adding the following code to your main.dart file:

void main() { removeHashFromUrl(); runApp(MyApp()); }

This code calls the 'removeHashFromUrl' function before running the application, ensuring that the URL does not contain a hash symbol when the user first loads the page.

And that's it! With these three simple steps, you can remove the hash symbol from the URL in your Flutter web application. This will make your URL more readable and improve your application's SEO.
