Adding a .title to a GeoJSON LineStringStyle Google Maps API Newbee here, I have successfully imported and displayed a GeoJSON from Firebase RTDB using the Google Maps SDK Util GeoJSON toolkit. If I import a point feature I can easily display a .title from the properties field. However, when the feature is a line or polygon there is no option to attribute a title. Question - are there any neat work arounds or other methods people have employed? The outcome is to have a title on each line or polyline Thanks Dave

How to make RTCPeerConnection be available in Kotlin/JS without declaring the class myself? I am trying out Kotlin/JS. As an exercice to learn something new I wanted to mess with WebRTC.

How to automatically go to the next EditText without lag I have 8 edittext fields. Each field is for 1 number (It's a phone number input screen). After 1 number is put in, I want my cursor to automatically move to the next edittext. But there is a delay in the input, making the user experience not smooth. I tried both: onEditorAction(EditorInfo.IME_ACTION_NEXT) and: secondNumber?.requestFocus() But no difference. This is a very common screen, so there should be a simple solution to this I assume? I'm not allowed to use external libraries....

The purpose of Compose, or at least...

Car Parking fee Our code consists of 3 stages. Stage 1 - In the car park, up to 5 hours fee is $ 1. Stage 2 - After 5 hours, it drops to $ 0.50 per hour. If the car stays in the park for 6 hours, the fee is $ 5.50. Stage 3 - the fee per day, taking into account the 1st and 2nd stages, is 14.50 cents. But we have to make the daily fee fixed as $ 15. If the car stays in the park for 25 hours, the price should be 15.50, not $ 15. I wrote stages 1 and 2 above, as you can see in the code block. However, I could...

What is the difference between Modifier.width(intrinsicSize.Min/Max) and Modifier.wrapContentWidth?
