Responsive for mobile apps?

Question

Mobile development

what does it mean to make a mobile application responsive? for the web, it was like this - there was a minimum screen width and the browser could pull the value wider and wider from this and the site should look acceptable throughout the gap.
how about mobile? I assume that the application should adapt to the most common resolutions (what???) in portrait and landscape orientations. although most applications do not respond to landscape rotation at all

, what else should be considered when laying out (native or flutter components) a mod for a mobile platform?

Thank you

It is necessary to layout in such a way that the application looks good at any resolution, the elements are stretched, narrowed, transferred, etc. Flutter has many widgets to facilitate these manipulations Expanded, Wrap, Stack, Positioned, GridView, etc.
You don’t take into account all the nuances, you just need to fill your hand and see how other applications look on each platform and start from current tasks. For example Drawer (hamburger menu) on android climbs over the window, and on ios it shifts the active window to the right, which in my opinion is more logical and more beautiful.
