📦 Installation
Maven <dependency >
<groupId > io.github.mdabdulkayum</groupId >
<artifactId > cmp-countrypicker</artifactId >
<version > 1.0.9</version >
</dependency >
Gradle (Kotlin DSL) implementation("io.github.mdabdulkayum:cmp-countrypicker:1.0.9" )
Gradle (Groovy) implementation 'io.github.mdabdulkayum:cmp-countrypicker:1.0.9'
🚀 Quick Start
1️⃣ Country Picker Bottom Sheet val pickerState = rememberCountryPickerState()
var isOpen by remember { mutableStateOf(false ) }
Button(onClick = { isOpen = true }) {
Text("Select Country" )
}
CountryPickerBottomSheet(
state = pickerState,
isOpen = isOpen,
onDismiss = { isOpen = false },
onCountrySelected = { country ->
println("Selected: ${country.name} " )
}
)
2️⃣ Phone Input Field (Basic) var phoneState by remember {
mutableStateOf(PhoneInputState())
}
PhoneInputField(
state = phoneState,
onStateChange = { phoneState = it }
)
3️⃣ Advanced Usage var phoneState by remember {
mutableStateOf(PhoneInputState())
}
PhoneInputField(
state = phoneState,
onStateChange = { phoneState = it },
defaultCountry = CountryRepository.getByIso2("BD" ),
countryFilter = CountryFilter.Whitelist(
setOf("BD" , "US" , "IN" )
),
allowFormatting = true ,
showCountryFlag = true ,
showCountryISO2 = true
)
🎨 Customization Easily customize the look and behavior:
PhoneInputField(
state = state,
onStateChange = { },
theme = CountryPickerThemeDefaults.light(),
showCountryCode = true ,
showCountryFlag = true ,
showCountryISO2 = false
)
Theme Support
Light / Dark themes
Custom typography
Custom colors
Shape customization
🔍 Country Filtering Control which countries are visible:
CountryFilter.All
CountryFilter.Whitelist(setOf("US" , "BD" , "IN" ))
CountryFilter.Blacklist(setOf("PK" , "AF" ))
📞 Phone Number Handling
✅ Parsing International Numbers val state = PhoneInputState.fromFullNumber("+8801712345678" )
Automatically detects country
Extracts national number
Applies validation
✅ Validation
Country-specific rules
Length validation
Optional regex support
✅ Formatting
Toggle formatting dynamically
Displays formatted output below input
🔴 Required Field Indicator Easily mark a field as required by adding * to the label.
The library will automatically render the * in red color , keeping your UI clean and consistent.
✨ Example PhoneInputField(
state = phoneState,
onStateChange = { phoneState = it },
label = "Phone Number *"
)
🎯 Behavior
"Phone Number" → displayed as normal text"*" → automatically styled in red
⚙️ How It Works The label is internally parsed and styled using AnnotatedString:
fun buildRequiredLabel (label: String ) return buildAnnotatedString {
append(label.replace("*" , "" ).trim())
append(" " )
withStyle(style = SpanStyle(color = Color.Red)) {
append("*" )
}
}
}
✅ Notes
No extra configuration required
Automatically applied when * is present
Ensures consistent required field indication across your app
