Becoming a full-stack developer requires a hand in all layers of the application development stack. This includes Frontend, Backend, Database and Infrastructure.
Google Cloud Platform is a suite of cloud computing services used by Google and external business for running various kinds of software. This platform contains relevant services allowing us to be effective in building full-stack applications.
In this mini course we will build an Image Upload Mobile App using a couple of Dart packages primarily gcloud and googleapis_auth. These packages provide a set of helper classes for connecting to Google Cloud Platform services.
We will be using the Flutter SDK to build our mobile app since it provides a great set of features and tools for building cross-platform mobile applications. It also makes sense to be using Flutter as it’s also written in Dart 😉
Getting started
We need to set up a Google Cloud Platform account. It’s free to set up and they’re currently offering $300 credit for 90 days. This will allow you enough time to use the Cloud Storage service for uploading images to.
The contents of the video are as follows:
- 00:00 Intro
- 00:19 App demo
- 00:57 Create a Google Cloud Project
- 01:32 Create a Cloud Storage bucket
- 02:11 Setup dependencies
- 02:43 Implement image picker
- 06:31 Create your IAM Service Account
- 07:51 Implement CloudApi Service class
- 09:34 Load IAM credentials into CloudApi Service
- 11:01 Make request to Google Cloud Storage
- 12:10 Set correct content type for image
- 14:31 Set custom metadata on image
- 15:08 Implement loading and uploaded state
- 16:59 Set bucket access permissions
- 17:46 Outro
Once you’ve set up a Google Cloud Platform account, create a Flutter project by running the following command:
$ flutter create new_project
Add the following packages under the dependencies key of your pubspec.yaml file:
dependencies: gcloud: ^0.7.3 googleapis_auth: ^0.2.12 image_picker: ^0.6.7+10 mime: ^0.9.7
Then run pub get to update your packages. Once you are setup, see the course for the full demonstration.
