Kotlin Multiplatform sample with SwiftUI and Compose (Desktop and Android) clients. Heavily inspired by Wordle game.
Kotlin Multiplatform sample heavily inspired by Wordle game and also Word Master and wordle-solver samples. The main game logic/state is included in shared KMP code with basic UI then in following clients
The shared WordMasterService
class includes following StateFlow
s representing the current set of guesses and updated status info for each letter.
val boardGuesses = MutableStateFlow<ArrayList<ArrayList<String>>>(arrayListOf())
val boardStatus = MutableStateFlow<ArrayList<ArrayList<LetterStatus>>>(arrayListOf())
The various clients call WordService.setGuess()
when a user enters a letter and then WordService.checkGuess()
after row of letters
are entered...UI then reflects any resulting updates to above StateFlow
's. The Compose clients for example do that using following (with any updates to those StateFlow's
triggering recomposition)
val boardGuesses by wordMasterService.boardGuesses.collectAsState()
val boardStatus by wordMasterService.boardStatus.collectAsState()
@Published public var boardStatus: [[LetterStatus]] = []
@Published public var boardGuesses: [[String]] = []
which are then updated using for example
let stream = asyncStream(for: wordMasterService.boardStatusNative)
for try await data in stream {
self.boardStatus = data as! [[LetterStatus]]
}
let stream = asyncStream(for: wordMasterService.boardGuessesNative)
for try await data in stream {
self.boardGuesses = data as! [[String]]
}
Any updates to boardStatus
or boardGuesses
will trigger our SwiftUI UI to be recomposed again.
