Converts Jetpack Compose UI into PDF files with layout auto-adjustment, sharing options, and future support for dynamic page sizes. Handles composables efficiently.
A Kotlin Multiplatform library for converting Jetpack Compose UI into a PDF file, supporting both Android and iOS. The library ensures that composables like LazyColumn are handled properly by using a Column to capture the full content.
Add the dependency to your build.gradle.kts file:
implementation("io.github.daanidev:pdf-kmp:1.0.2")
implementation("org.jetbrains.kotlinx:kotlinx-datetime:0.4.0")
Use the following code inside a composable function to generate a PDF file:
import kotlinx.datetime.Clock
import kotlinx.datetime.TimeZone
import kotlinx.datetime.toLocalDateTime
val scope = rememberCoroutineScope()
val currentTime = Clock.System.now().toLocalDateTime(TimeZone.currentSystemDefault()).time
val fileName = "test_pdf_${currentTime}"
Button(onClick = {
scope.launch {
PDFUtil.generatePdf(
fileName = fileName,
content = {
ShowList() // Your composable function
},
shareAfterCreation = false // Set to true to share after creation
)
}
}) {
Text("Click me!")
}
For Android, initialize the context inside the onCreate method of your Activity:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
ActivityContext.initializeActivityContext(this)
}
Additionally, add the following permissions to AndroidManifest.xml to allow storage access:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
Also, add the following inside your res/xml folder:
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path
name="external_files"
= />
And in your AndroidManifest.xml file inside the <application> tag:
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="replace with your authority"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
= />
