How to render a local HTML file with flutter dart webview

Question

I want to render a local HTML file stored in my phone memory in webview using flutter and dart.

Answer 1

You can pass a data URI

Uri.dataFromString('hello world', mimeType: 'text/html').toString()

or you can launch a web server inside Flutter and pass an URL that points to the IP/port the server serves the file from.
