Question 1

How to auto-play videos when scrolling in Flutter?

Accepted Answer

Use inview_notifier_list to detect when video widgets enter the viewport and trigger playback. Wrap video players in InViewNotifierWidget with a condition function, as shown in the auto-play video example GIF.

Question 2

inview_notifier_list vs scrollable_positioned_list?

Accepted Answer

inview_notifier_list focuses on custom visibility detection with condition functions, while scrollable_positioned_list is better for jumping to specific indices. Choose based on whether you need fine-grained visibility control or index-based navigation.

Question 3

How to throttle scroll events in Flutter for performance?

Accepted Answer

This package includes a `throttleDuration` property to limit scroll notification frequency. Set it to a duration like 200ms to reduce event calls and improve app performance, as mentioned in the properties section.

Question 4

Can I use inview_notifier_list with GridView?

Accepted Answer

No, it only supports ListView and CustomScrollView out of the box. For GridView, you'd need to adapt the code or use a different package, as it's not natively supported.

Question 5

How to handle dynamic lists with changing widget IDs?

Accepted Answer

You must manually manage unique IDs for each widget, which can be error-prone. Consider generating IDs based on index or data keys, but the package doesn't automate this, requiring extra code for dynamic content.

Question 6

Best practices for isInViewPortCondition in Flutter?

Accepted Answer

Define clear thresholds based on your UI needs, like checking if a widget is 50% visible. Use the provided parameters (deltaTop, deltaBottom, viewPortDimension) to create conditions, as demonstrated in the basic usage example.
