Pixelbin #

Pixelbin Dart library helps you integrate Pixelbin with your Dart/Flutter Application.

Usage #

Install using Pub Package Manager #

Run this command:

  • With Dart:
dart pub add pixelbin
  • With Flutter:
flutter pub add pixelbin

OR

  • This will add a line like this to your package's pubspec.yaml (and run an implicit dart pub get):
dependencies:
  pixelbin: ^latest_release_version

Creating Image from URL or Cloud details #

import 'package:pixelbin/pixelbin_dart_sdk.dart';
final PixelBinImage? imageFromUrl = PixelBin.shared.imageFromUrl(
        "https://cdn.pixelbin.io/v2/dummy-cloudname/erase.bg(shadow:false,r:true,i:general)~af.remove()~t.blur(s:0.3,dpr:1.0)/__playground/playground-default.jpeg");
debugPrint(imageFromUrl?.encoded);
// Create Image url from cloud, zone and other details
final PixelBinImage imageFromDetails = pixelBin.image(
          imagePath: imageFromUrl.imagePath, cloud: imageFromUrl.cloudName, transformations: imageFromUrl.transformations, version: imageFromUrl.version);
debugPrint(imageFromDetails.encoded);

Applying Transformations and Getting Transformations #

import 'package:pixelbin/pixelbin_dart_sdk.dart';
// Create Image url from cloud, zone and imagePath on cloud (Not local path)
final image = PixelBin.shared.image(imagePath: "example/logo/apple.jpg", cloud: "apple_cloud", zone: "south_asia");
      debugPrint(imageFromDetails.encoded); // https://cdn.pixelbin.io/v2/apple_cloud/south_asia/original/example/logo/apple.jpg
final eraseTransformation = Transformation.erasebg(); // Creating Erasebg Transformation
final resizeTransformation = Transformation.resize(height: 200, width: 200); // Creating Resize Transformation
image.addTransformations([eraseTransformation, resizeTransformation]); // Applying multiple transformations with list(keep passing all transformations in list)
// OR
image.addTransformation(eraseTransformation);
image.addTransformation(resizeTransformation); // Applying transformations one by one
final outputUrl = image.encoded; // https://cdn.pixelbin.io/v2/apple_cloud/south_asia/erase.bg()~t.resize(h:100,w:100)/example/logo/apple.jpg
debugPrint(outputUrl);

Uploading Image and getting url object #

// Signed Url and Field can be generated via using Backed SDK for pixelbin or API to generate signed url for upload
// Assume imagePath: "example/logo/apple.jpg", cloud: "apple_cloud", zone: "south_asia" & generate details
final signUrl = "SIGNED_URL";
final fields = {// Key: Value}; // META_DATA in value
final signedDetails = SignedDetails(url: signUrl, fields: fields)
// file is local picked file, other fields chunkSize: Int = 1024, concurrency: Int = 1
try {
     final signedDetails = SignedDetails(url: signUrl,fields:fields);
     final PixelBinImage? uploadResponse = await PixelBin.shared
          .upload(file: file, signedDetails: signedDetails);
     debugPrint("Response:=> ${uploadResponse?.encoded}");
    } catch (e) {
     debugPrint("Error:=> ${e.toString()}");
    }
Parameter Type Description
file (File) File File to upload to Pixelbin
signedDetails (SignedDetails) Object Signed details generated with the Pixelbin Backend SDK
chunkSize (Int) Integer Size of chunks to be uploaded in KB (default value is 1024)
concurrency (Int) Integer Number of chunks to be uploaded in parallel API calls
  • Resolves with Image object on success.
  • Rejects with error on failure.
