Build a Camera App : Flutter In-App Camera

In many apps we need users to upload images by clicking a picture. For that, we can use the default camera app of the device but what if we need to integrate an in-app camera? Well, that is also possible with flutter. The flutter team has developed a package called camera (https://pub.dev/packages/camera) which will let us do exactly this.

Let’s see how can we achieve this by a simple example.

Setting up the project

First of all, install the camera package into your project by adding the following line into pubspec.yaml file.

camera: ^0.8.1+3

— IOS Setup

IOS 10.0 or higher is required for this plugin.
Add the following lines in the Info.plist file to set things up.

<key>NSCameraUsageDescription</key>
<string>Can I use the camera please?</string>
<key>NSMicrophoneUsageDescription</key>
<string>Can I use the mic please?</string>

— Android Setup

Change the minimum Android sdk version to 21 (or higher) in your android/app/build.gradle file.

minSdkVersion 21

Now that our project set up is complete, we can start coding the app.
