Fantasy Premier League Kotlin Multiplatform sample using Jetpack Compose, Compose for Desktop and SwiftUI (and Room for local persistence)

Hi there 👋

I'm a software engineer based in Galway, Ireland 🇮🇪 and working for Neat 🇳🇴. Google Developer Expert for Kotlin.

Some more background

• Extensive experience working as a hands-on software engineer on mobile, desktop, server and embedded applicaitons.
• Developing for Android since 2010 (using Kotlin for last 7 years).
• Keenly interested in Kotlin Multiplatform and, in particular, when combined with use of Declarative UI frameworks like Compose and SwiftUI! Have given a number of talks and written various articles on the topic over the last 5 years (johnoreilly.dev). Have also created a number of related samples/templates. Two of these, PeopleInSpace and Confetti, are included in the official Kotlin KMP docs and, along with a number of the others, in the Google Dev Library. Several of the samples are also referenced in the docs of the libraries that they showcase.
• Gets things done!

Recomposition happens multiple time

PlayerDetailsScreen composable has been called multiple times;
Thus,

FantasyPremierLeague/app/src/main/java/dev/johnoreilly/fantasypremierleague/MainActivity.kt

Line 83 in 03e841e

val player = fantasyPremierLeagueViewModel.getPlayer(playerId)

get called multiple times.
Is that okay?
Is there a way to prevent these multiple recompositions?

Migrate from Combine to async/await

Crash on iOS when in airplane mode

It seems the iOS is crashing due to an issue with ktor throwing an Exception. Been scratching my head around this one and Android is fine since you can always catch the exception there in platform specific code.

What would be the best approach to handle this? should it be done in shared code or platform specific?

Uncaught Kotlin exception: io.ktor.client.engine.darwin.DarwinHttpRequestException: Exception in http request: Error Domain=NSURLErrorDomain Code=-1009 "The Internet connection appears to be offline."

Looks it was raised before. ktorio/ktor#1165

Use https://github.com/Kotlin/kotlinx-datetime in shared code

Parse fixture time using https://github.com/Kotlin/kotlinx-datetime and then show localized time in UI

Not able to build the project in Android Studio with the latest version (4.1.2)

When I tried to build the project in Android Studio, I got this error:
This version of the Android Support plugin for IntelliJ IDEA (or Android Studio) cannot open this project, please retry with version 4.3 or newer.

I tried the solution in the following StackOverflow questions but none of them is working:

1. https://stackoverflow.com/questions/53331462/this-version-of-android-studio-cannot-open-this-project-please-retry-with-andro
2. https://stackoverflow.com/questions/62678785/android-support-plugin-for-intellij-idea-or-android-studio-cannot-open-this-pr/65453722
