Flutter Cognito Plugin

An AWS Cognito plugin for flutter. Supports both iOS and Android.

Installation

First follow the regular flutter plugin installation on Dart Pub.

Make sure you have built the app once for both Android/iOS before continuing.

---

Since this plugin uses the native AWS sdk, the installation is a little more involved.

Android

Add an awsconfiguration.json file to android/app/src/main/res/raw/awsconfiguration.json.

This is what one should look like :-

{
    "IdentityManager": {
        "Default": {}
    },
    "CredentialsProvider": {
        "CognitoIdentity": {
            "Default": {
                "PoolId": "XX-XXXX-X:XXXXXXXX-XXXX-1234-abcd-1234567890ab",
                "Region": "XX-XXXX-X"
            }
        }
    },
    "CognitoUserPool": {
        "Default": {
            "PoolId": "XX-XXXX-X_abcd1234",
            "AppClientId": "XXXXXXXX",
            "AppClientSecret": "XXXXXXXXX",
            "Region": "XX-XXXX-X"
        }
    }
}

This plugin supports the amplify SDK for android and iOS, and the the amplify cli can be used to generate the awsconfiguration.json file.

Just do $ amplify init from the android & ios folder of your app.

iOS

Run $ pod init from the ios folder of your app.

Now, open ios/Podfile. Ensure ios version is set to a minimum of 9.0.

platform :ios, '9.0'

To add the awsconfiguration.json file to iOS module, you will unfortunately, need to open up your project in XCode.

1. Start Xcode
2. Click on ‘File > Open’
3. Select the ios/Runner.xcworkspace file.

Now just drag-drop the awsconfiguration.json file, from android/app/src/main/res/raw/awsconfiguration.json to XCode Runner (Right next to AppDelegate.swift).

Here is a video.

That should create a symlink to the file in the ios module, and bundle it into the final ios app.

This way you won't need to maintain 2 config files.

Usage

The plugin comes with a showcase app that will let you try all features; see if you setup the awsconfiguration.json correctly.

It's present in the usual example directory

$ git clone https://github.com/pycampers/flutter_cognito_plugin.git
$ cd flutter_cognito_plugin/example
$ flutter run
