Composed Barcodes
|
|
=================
|
|
|
|
Make barcode views with ease in Jetpack Compose.
|
|
|
|
|
|
Gradle users:
|
|
|
|
|
|
```
|
|
implementation("com.simonsickle:composed-barcodes:1.1.1")
|
|
```
|
|
|
|
Examples
|
|
--------
|
|
|
|
Displaying barcodes is super easy! Simply call the composable in your layout.
|
|
|
|
```kotlin
|
|
val URL = "https://github.com/simonsickle/ComposedBarcodes"
|
|
// Make sure the value is valid for the type of barcode selected. The library will
|
|
// just show an infinite spinner in place of a barcode if the data is not valid.
|
|
if (BarcodeType.QR_CODE.isValueValid(URL)) {
|
|
Barcode(
|
|
modifier = Modifier.align(Alignment.CenterHorizontally)
|
|
.width(150.dp)
|
|
.height(150.dp),
|
|
resolutionFactor = 10, // Optionally, increase the resolution of the generated image
|
|
type = BarcodeType.QR_CODE, // pick the type of barcode you want to render
|
|
value = URL // The textual representation of this code
|
|
)
|
|
}
|
|
|
|
// You must handle invalid data yourself
|
|
if (!BarcodeType.CODE_128.isValueValid(URL)) {
|
|
Text("this is not code 128 compatible")
|
|
}
|
|
```
|
