- Functionality in desktop. (Tested on Linux)
- Functionality in mobile (Tested on android)
- Fix: Background on new view does not properly match views before and after.
- Make sure text content and placement is consitent with rest of the app.
- Fix: Input field on Desktop becomes 0500 when trying to write 500.
- Error handling. Make sure all error scenarios are considered and handled properly. (Note: My experience in UI coding is limited but I am currently convinced this new feature will handle errors gracefully)

is there a need for checking for both 0 and '0'? I feel like it should always just be a value of one type. If that's not the case then it should be cast to one type first before checking.

Not really, I should ™️ be '0' its just me being defensive. Will fix.

I'm not sure this file really needs to be in this PR. It's useful but has nothing to do with this particular feature. I think this should be added in a follow-up PR.

Not sure why this is there or what it does... Probably got created when I was trying to set up the project/IDE. Will remove from this PR. Not really sure what it does but I can add it in a follow up PR if It would be useful.

@emiljoha it's used by VSCode to configure the built-in JS language service. See here for details: https://code.visualstudio.com/docs/languages/jsconfig

I wonder if the error from this try/catch block should be propagated further from this method so that the UI can display some useful info to the use and try to recover rather than just having a log message.

Thinking about it, that exception will only be thrown if we do not have a valid lightning invoice in the address field. That is dependent on other functions being called before this one. That kind of subtle and implicit dependencies are dangerous, IMHO. I have tried to make the expectations of the method more clear both in code and documentation.
PS: I am used to writing functional Typescript code in my day job, so all this state and no typing is making me a bit uncomfortable.

Wonky description here: If zero use the amount specified in the invoice as a lightning transaction and display the wait screen while the payment confirms. doesn't really make sense.

Will try to make it more clear.
Detecting a zero amount invoice in checkType we redirect to a seperate view. Currently only title is changed in the view.
Amount will be an empty string when user have not specified in the view before pressing "pay".
