QUESTION
I implemented PageView parallax effects in Flutter using github repo page-transformer . After Null safety migration I am facing the error below.
...ANSWER
Answered 2022-Mar-02 at 18:53Here is the problem, you have this variable: final ScrollMetrics _pageMetrics;
which is not nullable, on initialization, you assign it to this other variable ScrollMetrics? metrics
, which is nullable. The error you get happened because metrics
was null and you tried to assign it to _pageMetrics
.
So why is metrics
null? Well, you are supposed to pass the value of metrics on the constructor, but you didn't on this line:

Answered 2022-Feb-24 at 05:49You can utilize the position
parameter, that maps to the current position of the page, to get a color shade based on the page position; this also will benefit in grading the colors between the most darken & most lighten colors so that the color changes gradually:
- Create two color resource for the lighten color and darken colors
- Use
ColorUtils.blendARGB()
to get a color based on percentage of the position. - Set the new background color to the root view of the
page

How can I create an animation similar to the stock android launcher animation applied to apps when you change homescreen pages.
Here's a gif: https://i.stack.imgur.com/Zh7qE.gif
As the page swipes, the icons slightly overshoot their mark, and settle back to the center. I don't see how I can do that with a PageTransformer and I can't find any resources to point me in the right direction.

I'm thinking of using the onClickAttribute but I have no idea how to do this.

ANSWER
Answered 2020-Dec-13 at 13:49I will try to explain how to pass data by passing image position from MainActivity to detailedActivity.
I use the following way: First, make an interface with a method name onPictureClicked()
then implement that interface in your MainActivity to override onPictureClicked()
. Call this method in your adapter. like: interface.onPictureClicked(int picturePositon)
Interface.java

Answered 2020-Sep-15 at 08:16I honestly didn't find a true mean to make Viewpager2 works with swiping events on left and right preview since Viewpager2 class is final. But things worked out very well with using NestedScrollview.
QUESTION
I received help a while ago by a hero that helped me make a Toolbar
disappear when an ImageView
was clicked by using a callback function and an interface. I have copied this kind of algorithm for a different page view adapter and it works completely fine in the starting page adapter, but when I switch it, the toolbar doesn't disappear and reappear even though the tapping works. I have tried this for a while, but no luck. Any help will be appreciated.

Here is what I was trying to do. addNewQRCard() is onclick event fired by a button to add new images to viewpager. I have to always set the adapter to new items.

QUESTION
I need some help with a PageTransformer for ViewPager2.
I have 3 pages in my ViewPager2. Each page should be overlapped by the next. In addition, the pages should all be firmly in the middle and only be slidable to the side.
Example:
Page 1: blue color
Page 2: purple color
Page 3: green color
Page 1 is overlapped by Page 2 and page 2 is overlapped by Page 3.
I have set that the 3rd page can be seen first by setting the currentItem to 2
You can see the green page and if you push it to the right you should be able to see the purple page (even while pushing) If you then push the purple page to the right you should see the blue page And the pages should not move (except to the side of course)
Something similar to this but the overlap the other way around because i start at page 3 and without changing the scaling. (The alpha change is totally okay and wanted)
I hope someone can help me and thanks in advance
