eliud #

Documentation for eliud is under construction. Please be patient.

  • Eliud technology is open source technology.
  • The technology allows to build apps and/or websites. Today, app content can include photo galleries, pages with videos and images (html), social media, chat with or between members, your shop / shopping cart, photo sliders, documents, and more. A complete list below.
  • Eliud is a layer on top of Flutter. Flutter is an open-source UI software development kit created by Google. Flutter allows to develop cross platform applications for iOS, Android and web. Flutter supports Linux, macOS, Windows and Google Fuchsia. This hasn't been tested with eliud packages yet.
  • For those who know Worpress: Eliud is to Flutter as Wordpress is to html:
    • Html allows you to construct webpages. However, html requires some level of technical knowledge about building webpages.
      • Wordpress and many other similar technologies allow people without knowledge of html to build webpages and websites.
    • Flutter allows to build websites and apps, or even Windows, Linux, macOS and Google Fuchsia apps. However, Flutter requires programming skills and technical knowledge.
      • Eliud allows people without programming skills and technical knowledge to build cross platform apps and websites.
  • Eliud is pluggable technology, allowing developers
    • to extend / add functionalities by means of plugins / packages.
    • to change look and feel through using styles.
  • A website / app built with Eliud consist of its core Eliud package + one or more Eliud plugins. The app is constructed by configuring it. Configuration, images and videos are stored in Firebase database and Firebase storage.

Example Eliud apps #

These are some example apps which demonstrate what eliud can give you. Everything used is open source, part of eliud project.

Logo Thoma5 - Profile of Thomas. Under construction In development In development https://thoma5.com

Quick start #

This guide are all steps to create a minimum android, iOS or web app with Eliud.

Whenever this pops up, make note of this for what this is in your case, as you'll need it at some later stage. In the below text we provided this information whilst creating thoma5. Obviously for sensitive information, like passwords, we've provided fake info.

Step 1: Create a new google account #

  1. Goto https://www.google.com/account/about/

  1. Then follow onscreen instructions. Then store the key-file in a safe place. You will have to use it multiple times in the future.

  2. Now run:

keytool -list -v -alias your_keystore_alias -keystore your_keystore_filename -storepass your_keystore_storepass -keypass your_keystore_keypass

For example:

  5. Specify your android app nickname
  6. Paste the SHA-1 key from step 7: Your keystore SHA1
  7. Press "Register app"
  8. Then download the file google-services.json

Step 9: Create Android Studio project #

    6. Android language: Should be Java
    7. iOS language: Should be Swift
    8. Platforms: Should be Android, iOS and Web

    ❗ IMPORTANT ❗

    The android package name specified in step 8 Your Android app package name - e.g. com.thoma5.thoma5_app - should be equal to the concatenation of organisation - e.g. com.thoma5 - a dot and the project_name - e.g. thoma5_app

  5. Press finish

Step 10: Copy google_services.json #

  1. Switch to the Project view in Android Studio to see your project root directory.
  2. Move your downloaded google-services.json file from step 8 into into your module (app-level) root directory, e.g. thoma5_app/android/app

Step 11: Apply firebase SDK instructions #

  1. Goto https://console.firebase.google.com
  2. Select your project
  3. Find your app from "your apps" section, then press "See SDK instructions"
  4. You get to chance to re-download the google_services.json file, skip this by pressing next.
  5. Now apply the suggestions provided. Make sure to select Groovy (build.gradle) and Java.

🤔

At the time of writing this document, the changes to make were:

file location add
1️⃣ thoma5_app/android/build.gradle buildscripts > dependencies classpath 'com.google.gms:google-services:4.3.15'
2️⃣ thoma5_app/android/app/build.gradle plugins id 'com.google.gms.google-services'

:three: Finally the below at the bottom of thoma5_app/android/app/build.gradle had to be added 


dependencies {
    // Import the Firebase BoM
    implementation platform('com.google.firebase:firebase-bom:32.2.2')


    // TODO: Add the dependencies for Firebase products you want to use
    // When using the BoM, don't specify versions in Firebase dependencies
    implementation 'com.google.firebase:firebase-analytics'


    // Add the dependencies for any other desired Firebase products
    // https://firebase.google.com/docs/android/setup#available-libraries
}

Step 12: Add key store file to your project #

  1. Create key.properties file in your android directory, e.g thoma5/android/key.properties

  2. Populate it with the below keys and values as below. Find your values from step 7, i.e.

    1. storeFile=Your keystore filename
    2. storePassword=Your keystore storepass
    3. keyPassword=Your keystore keypass
    4. keyAlias=Your keystore alias

    e.g.

    storePassword=abc
keyPassword=cde
keyAlias=thoma5key
storeFile=c:/Users/thomas/.android/thoma5.keystore

  3. Add the following lines to your android apps build.gradle file, e.g. thoma5/android/app/build.gradle

    1. Load the properties
    plugins {
   ...
}
   
// add this after plugins
def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}

// the rest of the file   
...
    1. Use the keystore for signinConfigs
    android {
    defaultConfig {
       ...
    }

    // add this after defaultConfig and before buildTypes
    signingConfigs {
        release {
            keyAlias keystoreProperties['keyAlias']
            keyPassword keystoreProperties['keyPassword']
            storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
            storePassword keystoreProperties['storePassword']
        }
    }

    buildTypes {
       ...
    }
}
    1. Make sure your buildTypes is pointing to the releasing signingConfigs for both debug and release builds
    buildTypes {
     release {
         signingConfig signingConfigs.release
     }
     debug {
         signingConfig signingConfigs.release
         debuggable true
     }
}

Step 13: Update pubspec.yaml #

TODO -> see file pubspec.yaml in thoma5 project

and press Pub get

Step 14: Update main.dart #

TODO -> see file main.dart in thoma5 project

Step 15: Clean up #

TODO

  1. Delete test directory, which contains widget_test.dart

Step 16: minSdkVersion #

  1. Goto your Flutter SDK path, specified in step 9, subdirectory packages\flutter_tools\gradle\src\main\groovy and edit the file flutter.groovy and open it

  2. Update the value for minSdkVersion to be 21

    class FlutterExtension {
    ...

    /** Sets the minSdkVersion used by default in Flutter app projects. */
    static int minSdkVersion = 21

    ...
}

    ❗ REMARK ❗

    We only need to make this change to the minSdkVersion for the SDK 1 time, i.e. do not repeat this step for future projects / apps.

Step 15: Run your app #

  1. Run the app. Because this is the first time your start the app, it will install a basic app.
  2. When the app asks to choose an account to login, select the Google account you created in step 1
  3. Ones the basic app is created, it will open

Step 16: Add some basic functionality to your app #

TODO

  1. Use the wizards
  2. Point to minkey docs to configure the app
