Change Flutter Web Appearance in Google Search result

Heyhow,

I am building a website with Flutter Web and i want to change the Name in Google Search (Picture 1) the Slogan/text in Google Search (Picture 2) and the text and icon in the Tap of the Browser(Picture 3).

Is this possible without building a new project ore at least some of them? Thanks for any help
