}

Multiplatform Projects

Add the dependency to your commonMain source set:

kotlin {
    sourceSets {
        commonMain {
            dependencies {
                implementation("io.github.joelkanyi:komposecountrycodepicker:<latest-version>")
            }
        }
    }
}

Android Projects

Add the dependency to your app's build.gradle.kts:

dependencies {
    implementation("io.github.joelkanyi:komposecountrycodepicker:<latest-version>")
}

Gradle Version Catalog

Add the following to your libs.versions.toml:

[versions]
komposecountrycodepicker = "<latest-version>"

[libraries]
komposecountrycodepicker = { module = "io.github.joelkanyi:komposecountrycodepicker", version.ref = "komposecountrycodepicker" }

Then add the dependency in your build.gradle.kts:

dependencies {
    implementation(libs.komposecountrycodepicker)
}

Quick Start

Use the picker in your Composable:

var phoneNumber by rememberSaveable { mutableStateOf("") }
val state = rememberKomposeCountryCodePickerState(
    showCountryCode = true,
    showCountryFlag = true,
)

KomposeCountryCodePicker(
    modifier = Modifier.fillMaxWidth(),
    text = phoneNumber,
    onValueChange = { phoneNumber = it },
    state = state,
)

Fully Custom Text Field

If you have your own design system and want to use your own text field, use CountrySelectionDialog and state.selectedCountry directly:

@OptIn(RestrictedApi::class)
@Composable
fun PhoneNumberField() {
    var phoneNumber by rememberSaveable { mutableStateOf("") }
    var showCountryPicker by rememberSaveable { mutableStateOf(false) }
    val state = rememberKomposeCountryCodePickerState()

    if (showCountryPicker) {
        CountrySelectionDialog(
            countryList = state.countryList,
            containerColor = MaterialTheme.colorScheme.background,
            contentColor = MaterialTheme.colorScheme.onBackground,
            onDismissRequest = { showCountryPicker = false },
            onSelect = { country ->
                state.setCode(country.code)
                showCountryPicker = false
            },
        )
    }

    OutlinedTextField(
        modifier = Modifier.fillMaxWidth(),
        value = phoneNumber,
        onValueChange = { phoneNumber = it },
        placeholder = { Text("Phone Number") },
        keyboardOptions = KeyboardOptions(keyboardType = KeyboardType.Phone),
        leadingIcon = {
            Row(
                modifier = Modifier
                    .clickable { showCountryPicker = true }
                    .padding(start = 12.dp, end = 8.dp),
                verticalAlignment = Alignment.CenterVertically,
            ) {
                Image(
                    modifier = Modifier.width(28.dp).height(18.dp),
                    painter = painterResource(state.selectedCountry.flag),
                    contentDescription = state.selectedCountry.name,
                )
                Spacer(modifier = Modifier.width(6.dp))
                Text(text = state.selectedCountry.phoneNoCode)
            }
        },
    )
}
