ProgressCircle | ProgressCircle makes generating circular progress meters | Animation library

Code:

Snack I have rendered a chart in rn along with tooltips. Clicking on each individual dot in the chart renders its own separate tooltip component. Currently, the way I have written it down, clicking on Dot 1, all corresponding tooltips get dropped-down at the same time. For instance, if I click on Dot 1, all corresponding tooltip components dropdown-

I want only the first tooltip component to dropdown if I click on Dot 1. Is there any way to accomplish that?

I've got the following code below which I use to create a List with a circle in each element.

My goal is to have a "circle fill animation" when the view is opend. In this case, the blue color should fill to the given percentage level. The Circles and List are working, however my animation is not kicked off when the List is loaded / the user accesses the view.

Any ideas what I'm doing wrong?

I'm trying to render a shape in the center of Circle, a custom subclass of UIView (first snippet). Then I'm adding the Circle as a subview in my VC and adding constraints (second snippet).

When height and width is constrained, the rendered shape has its center (undesirably) in the top left corner of the Circle view (picture bellow). When only X and Y of the Circle view are constrained, the shape is in center as expected.

Why does this happen and what do I do to be able to constrain Circle as I please but still have the shape render in the center of Circle ? Thanks.

I am building a React Native app and am trying to create a timer. The timer runs normally in the foreground using setInterval and updating a bit of state that holds the amount of seconds and decreases it every one second. When the app is backgrounded the date is captured and stored. When the active is made active again I am trying to calculate the difference between the two dates and then updating the state to reflect the difference so it appears to the user that the timer is running in the background.

I am running into an issue where the state is not updated when the timer is running.

I have a simple started project in react and I am trying to use conic-gradient in react. Here is the code :

I have a react native code, using expo, with a graph with text. In Apple, this application is showing it twice. In Android, once.

Here is the code:

I'm an Android developer trying to learning UWP development, and attempting to use the Prism Library and Windows Template Studio to help me with the boilerplate functionality.

My goal is to have a ProgressCircle control that is accessible by all views, so that whenever I'm performing an async call, I can pop up the ProgressCircle. In an attempt to keep things DRY I don't want to have a ProgressCircle in each view. How can I achieve this?

As I understand it (Prism) as built by the Windows Template Studio has a ShellPage view that houses all of the other views within it and it has it's own viewModel. This seems somewhat similar to Androids Activity/Fragment model. My initial idea was to place the ProgressCircle in the ShellPage view, and then call it from my child view (MainPage) when needed. However I have not figured out how to call another views viewModel methods from a child/other view/viewModel. Is this the correct approach and if so how can I accomplish this?

My other idea is to create a Progress app service that can be added to the viewModel base class, but I haven't learned about app services just yet.

I am trying to create 2 layers that stack on top of each other and are inside of a custom view class.

the drawing for the layers is working great but I just can't get them to adjust their location based on the location of the view which has been set using auto layouts where the view is created in code (no IB).

I have tried changing the frame of the layer with a call to layoutSubviews here is the code for the try.
