Flutter animated add button

I am currently learning flutter and trying out different things. Not too long ago I discovered the app "Reflectly". I wonder how it is possible to create such an "add button" with animation.
Reflectly add button
Two possibilities for implementation have crossed my mind.
With the help of a stack widget and 4 shapes, 2 for the BottomBar and 2 for the button. The button would have an animation and enlarge and also move. However, this sounds a bit complicated for such a button.
The whole thing is a drop menu, but I don't know how to get such a shape with matching animation. Especially, these two things don't make it easy for me to imagine how to implement such a button.
Does anyone have an idea?
You can achieve this by the following
Create 2 different paths. 1 is for the center button and the second one is the custom shape that you wish to see as the output when the button is clicked. Then use an animated builder and change shape when clicked

How to drag / re-center the displayed Tableau worksheet?

Suppose I wish to focus on the state of Colorado in the following chloropeth map:
The typical mechanism is to use the operating-system dependent means of dragging the picture. I am on OS/X so that involves using two fingers to drag the image to the desired new centering location.
However the actual result of that operation is a bounding box is displayed on the image (I can not get a screenshot of it since it disappears)
So then .. how to drag /re-center the Tableau display?
Click onto the small 'play' arrow button on the chart menu in the top left hand corner. A sub menu will pop up where you can select the scroll method you'd like - click and drag is one of these. You can also disable this through the chart options (the small drop down menu on the top right hand corner of the chart).

Mapbox toggle layers > double click required to hide layer?

I have followed the mapbox toggle layers demo (https://www.mapbox.com/mapbox-gl-js/example/toggle-layers/) on my map project.
In order to turn a layer 'off', I need to click twice on the actual button - once to select, and then a second time to actually hide the layer.
The demo map only requires a single click to show/hide layers.
How can I fix this?
