Display locally stored html file in assets folder on browser in Flutter Web

Question

Most answers I've seen are for mobile, but is there a way to open an HTML file stored in the asset folder on the browser in the flutter web? I've tried URL launcher but couldn't find a way to get the URL of where the asset is stored. A bunch of other solutions points back to WebView on mobile but my ask is more related to the web. Any ideas?

Solution

You need to do two things:

1. Store the HTML not in assets but in the /web folder where the index.html is.
2. Use url_launcher plugin to launch the address.

For example, imagine you have a privacy.html file you want to open from your Flutter Web app. Copy it to the /web folder in your project. Then use url_launcher and call to launch():

launch('/privacy.html')

This will open a new browser tab with the HTML page.
