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 resizeTransformation = Transformation.tResize(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(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()}");
    }
