Flutter text animation on page view scroll - flutter

Reference link: https://dribbble.com/shots/15798418-Mobile-App-Onboarding
I have been trying to build the above UI using Page view. I have used the stack as parent widget and handling the image scroll using page controller offset value.
Not sure how to achieve the text animation(In and out) and what could be the trigger point to start the animation for current page?

The animations package from the Flutter team has a nice package that includes an animation that closely resembles your example.
Here is the package: https://pub.dev/packages/animations
It is the first example under Shared Axis. They also have good examples of how to implement the animation using this package. If you have issues using the package please add some code samples for the problem and we can help!

Paging by item Flutter

i would like to achieve pagination with flutter like this: every swipe gesture there i only one page swipped, and it is being centered in the screen. on the edges of the screen you can see parts of the next and previous items i.e the item is NOT THE SIZE OF THE SCREEN. this requirement is important. i can't set the item to be the size of the screen, also it should have padding between the items. for a better understanding i have a gif attached.
Thank you.

You can achieve the goal easily using PageView widget.
Ive found a class carousel_slider which is easily making that functionallity under the hood using PageView as suggested above.
For anyone who will need such behaviour as in the gif, see https://pub.dev/packages/carousel_slider

Centered carousel without snapping in flutter

I'm trying to make a carousel-like view here using SingleChildScrollView, I want the item to snap in the middle of the screen when scrolling, one item at a time.
I would personally recommend using the carousel_slider package, which provides a lot of flexibility: You can use custom widgets and views, and create both horizontal and vertical carousels.

Alternatively, if you'd want to create it yourself, I think you'd have to try around working with custom ScrollControllers. Maybe take a look at the source code of the aforementioned package for some pointers.

How to produce this menu effect in flutter?<image attached>

This effect
I couldn't find any ways to produce this type of home screen card slide menu effect or any combination of widgets to reproduce this, sure could use some help.
This type of custom Drawer done with Stack, AnimatedBuilder and Transform. Most difficult part there is gesture behavior, that could be copied from original Drawer flutter source code.
Marcin SzaƂek represented this implementation, alongside with few other features on Flutter Europe.
At this video he describes how he done it.
And this is link to his github with this feature code implemented.

How to use Fade Scale of animations package for SnackBar?

In Readme of the animations package, I can see the fade scale transition working not only for a modal popup like AlertDialog but also for non-modal SnackBar, but could not find any detailed documentation on it. Files in example and test directories don't have related code either.
It looks like the fade scale transition provides only FadeScaleTransition and FadeScaleTransitionConfiguration; the former is for its (normal) child widget and the latter is for a modal dialog. SnackBar is neither of them, and I couldn't use it successfully although I tried in many ways.
Has anyone figured out how to use the package for SnackBar?

flutter-mapbox-gl Style is not coming

"I"m integrating MapBox in my existing flutter app, and I am able to see the Map, and can hover over the map, it changes it coordinates and other embedded features. However, the style is not coming, ie, map is not displayed properly.
I am just trying to get the minimum workable Map, so I can add desired features on top of that.
When I run the code as it is, from https://github.com/tobrun/flutter-mapbox-gl , as a new project on IntelliJ Idea, it all looks fine.
So it seems like, style is missing, but I can't figured out what else to include.
I copied map_ui.dart code in my class, and calling the class from home page of our flutter app.
Apart of this, I added, mapbox_gl: ^0.0.3 dependency in pubspec.yaml file
I expect the following
Output Map
. However, my code is displaying the following
Current Map

[edit:] Updated the current screen shot, after wrapping the widget in a Scaffold
So after wrapping the widget in a Scaffold, this is looking good now!
And, I had to zoom in a bit to see the image.
