如何在kotlin android中将base64字符串转换为图像

import android.graphics.Bitmap
import android.graphics.BitmapFactory
import android.util.Base64

fun base64ToImage(base64String: String): Bitmap? {
    val decodedBytes = Base64.decode(base64String, Base64.DEFAULT)
    return BitmapFactory.decodeByteArray(decodedBytes, 0, decodedBytes.size)
}

val base64String = "your_base64_string_here"
val imageBitmap = base64ToImage(base64String)
