Gradle

    implementation 'com.github.stevdza-san:OneTapCompose:1.0.0'
}

        maven { url 'https://jitpack.io' }
    }
}

Usage

Before you can use this library, you need to create a new project on a Google Cloud Platform. You need to create OAuth Client ID (ANDROID & WEB), because you will need that same Client ID (WEB), in order to implement One-Tap Sign in with Google.

After that, just call OneTapSignInWithGoogle() function, and pass that same information you’ve obtained through Google Cloud Platform. You will also pass OneTapSignInState, because that state is used later to trigger One-Tap dialog.

    val state = rememberOneTapSignInState()
    OneTapSignInWithGoogle(
        state = state,
        clientId = "YOUR_CLIENT_ID",
        onTokenIdReceived = { tokenId ->
            Log.d("LOG", tokenId)
        },
        onDialogDismissed = { message ->
            Log.d("LOG", message)
        }
    )

To trigger One-Tap dialog, just call open() function.

Button(onClick = { state.open() }) {
    Text(text = "Sign in")
}

Troubleshoot

In some cases you may encounter “Google Account not Found.” message inside onDialogDismiss lambda, even if you have already connected a Google account on your Android Emulator. Android emulators are prone to that issues (Not sure why and when that’s gonna get fixed). My suggestion in that case is to try and add a Google account on some other Android Emulator. If that doesn’t work either, then use a real device instead.
