Screen readers cannot list or move focus to elements outside of the current viewport

Steps to reproduce

NVDA, JAWS, and VoiceOver Screen readers cannot list or move focus to elements outside of the current viewport. Any elements that have scrolled out of view or haven't yet been scrolled into view will NOT be reachable via screen reader basic keyboard commands for reading and navigating web content.

Examples:

Function	JAWS Shortcut	NVDA Shortcut	VoiceOver Shortcut
Next Heading	H, 1-6 for heading level	H, 1-6 for heading level	Control Option Command H
List Headings	Insert F6	Insert F7 to open Elements list, Select the "Headings" radio button	Control Option U, Press left/right arrow keys until the "Heading" menu is displayed
Next Link	U for unvisited link, V for visited link	K for link, U for unvisited, link V for visited link	Control Option Command L for link, Control Option Command V for visited link
List Links	Insert F7	Insert F7 to open Elements list, Select the "Links" radio button	Control Option U, Press left/right arrow keys until the "Links" menu is displayed
Next Button	B	B	N/A
List Buttons	Control Insert B	Insert F7 to open Elements list, Select the "Buttons" radio button	Control Option U, Press left/right arrow keys until the "Form Controls" menu is displayed
Next Form Control	F	F	Control Option Command J
Next Table	T	T	Control Option Command T
Next Landmark	R	D	N/A
Next List	L	L	Control Option Command X

Expected results

• The "Next" keyboard shortcuts should move the screen reader focus to the next element of that type which exists on the page, not just the elements displayed in the current viewport
• The lists should contain all elements of that type which exist on the page, not just the elements displayed in the current viewport

Actual results

• The "Next" keyboard shortcuts only move the screen reader focus to the next element of that type which is displayed in the current viewport
• The lists only contain elements of that type which are displayed in the current viewport

Thanks for the report @jcollins-disney
Can you provide flutter doctor -v to know on which version are you seeing this behavior ?
Are you referring to windows and macos desktop + web platforms for this ?
Can you also take a look at this issue and open issues listed in this comment to check if they resemble your case or not ?

@darshankawar:

• I've added the flutter doctor -v info to the summary above
• Yes, this is Windows and macOS desktop web
• Issue 83809 seems to be unrelated to the issue I've listed on this ticket
