FAB | Quadrotor platform autonomously controlled with an Android

So I've been following the official tutorial here and I require a slide indicator here as well so I just copied and modified the code from this example here.

My markup looks like this:

I use the Shariff solution with an statistics backend to provide visitors with an easy way to share content on social media.

Based on the data from the statistics backend, Shariff will dynamically (JavaScript) introduce a 0 element to every share provider (e.g. Facebook, Twitter, ...), which has a related share count number in the statistics backend data.

Now, I would like to style every Shariff button, which does not have a share_count element, using only CSS.

This is how an Shariff button with a share count looks like in HTML:

As a developer one needs to adapt to change, I read somewhere it says:

If you don’t choose the right architecture for your Android project, you will have a hard time maintaining it as your codebase grows and your team expands.

I wanted to implement Clean Architecture with MVVM

My app data flow will look like this:

Model class

This was my earlier question where it was solved using multiple distribution.

I want to plot the continuous variable like age or tumor mutation burden as shown in first figure with a range like a window such 20-30 age group or some mutational burden range

The frequencies are calculated for all the variables of the metadata, but when plotting the age is not mapped to the final plot as show in the second plot.

Does the age need to be converted into other class before plotting?

I'm trying to hide a button when the link within the button is not found or the link value is "none". With the code below I'm seeing the text and link have been removed but part of the button is still visible. This is what I'm seeing

I am using the functions defined here: Extreme value analysis and user defined probability functions in Stan for modeling the data with a generalized pareto distribution, but my problem is that my model is in a for-loop and expects three real valued arguments, whereas, the gpd functions assume a vector, real, real argument.

I’m not so sure that my model chunk is so amenable to being vectorized, and so I was thinking I would need to have the gpd functions take in real valued arguments (but maybe I’m wrong).

I’d appreciate any help with switching the code around to achieve this. Here is my stan code

I was calculating e^x using Taylor Series and noticed that when we calculate it for negative x absolute error is large.Is it because we don't have enough precision to calculate it?

(I know that to prevent it we can use e^(-x)=1/e^x)

for some reason, only 'Cart' text is clickable on the following button. I've tried several different variations, but I can't seem to make whole button clickable. Thank you for any suggestions.

According to the docs, we can disable the FAB by setting null to its onClick:

onClick - will be called when user clicked on this FAB. The FAB will be disabled when it is null.

When I tried it I stumbled across that the onClick parameter is not nullable,

So, how to disable the FAB?
