This page is not a tutorial, just notes.

##1. Configure Android See https://firebase.flutter.dev/docs/installation/android
On first launch Android Studio returns errors:

Cannot fit requested classes in a single dex file (# methods: 94212 > 65536) Manifest merger failed : uses-sdk:minSdkVersion 16 cannot be smaller than version 18 declared in library Warning: Mapping new ns http://schemas.android.com/repository/android/common/02 to old ns http://schemas.android.com/repository/android/common/01 E/flutter (11479): [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: [core/not-initialized] Firebase has not been correctly initialized. Have you added the "google-services.json" file to the project?

Open android/app/build.gradle and add multiDexEnabled true in defaultConfig :

defaultConfig {
multiDexEnabled true // Added applicationId "rk.doleances" minSdkVersion 18 // Changed from 16 to 18 targetSdkVersion 30 versionCode flutterVersionCode.toInteger() versionName flutterVersionName }

Firebase has not been correctly initialized.

% cp google-services.json android/app

Edit android/build.gradle

buildscript { dependencies { // ... other dependencies classpath 'com.google.gms:google-services:4.3.8' // Added } }

Edit android/app/build.gradle

apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle" apply plugin: 'com.google.gms.google-services' // Added

Build > Flutter > Build App Bundle

##2. Configure iOS See https://firebase.flutter.dev/docs/installation/ios
Get GoogleService-Info.plist from Firebase console https://console.firebase.google.com/

Cocoapods bugs !

% pod install
/Library/Ruby/Gems/2.6.0/gems/ethon-0.14.0/lib/ethon/curls/classes.rb:36: [BUG] Illegal instruction at 0x0000000104584000

Closed : CocoaPods/CocoaPods#10893

Cocoapods deprecated settings

[!] Automatically assigning platform iOS with version 9.0 on target Runner because no platform was specified. Please specify a platform for this target

FlutterFire bugs

GeneratedPluginRegistrant.m:10:9: Module 'cloud_firestore' not found If you know how to fix please tell me...\

Steps:
% rm -rf ios
% flutter create .
% cp GoogleService-Info.plist ios/Runner/
% open ios/Runner.xcworkspace
Top left, double clic on Runner to open Editor (File Runner.xcodeproj)
Runner / Project / Runner / iOS Deployment Target : 14.0 (or 15.0)
Runner / Targets / Runner / Signing @ Capabilities : => Set Team
Runner / Targets / Runner / General / Display Name : Doléances
Runner / Targets / Runner / General / Bundle identifier : rk.doleances
flutter pub run flutter_launcher_icons:main

Top left, right clic on Runner
Add files to "Runner..."
Select ios/Runner/Runner/GoogleService-Info.plist

Top middle, clic on Runner > Edit Scheme...
On the left clic on Run / Run and select Build Configuration : Release Take your time... Xcode build done. 244,8s

Bugs :
The current Dart SDK version is 2.13.4.
Because doleances depends on image_picker >=0.8.4+2 which requires SDK version >=2.14.0 <3.0.0, version solving failed.
=> remove image_picker
Because shared_preferences 2.0.8 requires SDK version >=2.14.0 <3.0.0 and no versions of shared_preferences match >2.0.8 <3.0.0, shared_preferences ^2.0.8 is forbidden.
=> remove shared_preferences
Specs satisfying the Firebase/Firestore (= 8.6.0), Firebase/Firestore (= 8.8.0) dependency were found, but they required a higher minimum deployment target. Error running pod install

1/ Delete the Pods directory, the /ios/podfile.lock, and the ios/Flutter/Flutter.podspec
% rm ./ios
2/ Run pod deintegrate
% cd ios
% pod deintegrate
Deintegrating Runner.xcodeproj
Removing Pods directory.
Project has been deintegrated. No traces of CocoaPods left in project.
% cd ..
3/ Delete all of the contents inside your DerivedData folder.. you can run rm -rf ~/Library/Developer/Xcode/DerivedData/*
% rm -rf ~/Library/Developer/Xcode/DerivedData/*
4/ Run flutter clean
% flutter clean
5/ Run flutter pub get
% flutter pub get
6/ Run flutter build ios. Note thas this will also run the pod install command.
% flutter build ios
7/ Close your editor, and open your Runner.xcworkspace on XCode and run your XCode. Clean your build folder. If there's an option to update your project settings, accept it.
% open ios/Runner.xcworkspace \

##3. Configure Firebase ###3.1 Create Firebase base https://console.firebase.google.com/?hl=fr then :

• Retrieve google-services.json and put it in android/app/ next to build.gradle
• Edit android/build.gradle to add classpath 'com.google.gms:google-services:4.3.10'

  dependencies {
  classpath 'com.google.gms:google-services:4.3.10' // Added

• Open android/app/build.gradle and add 2 lines :
• Add apply plugin: 'com.google.gms.google-services'

  apply plugin: 'com.android.application'
  apply plugin: 'com.google.gms.google-services' // Added

• Add implementation platform('com.google.firebase:firebase-bom:28.4.0')

  dependencies {
  implementation platform('com.google.firebase:firebase-bom:28.4.0') // Added

###3.2 Register Firebase rules Create rk.doleances Start in production mode Define Cloud Firestore : eur3 (europe-west)

• Authentification / Sign-in method
  Activate Adresse e-mail/Mot de passe // Mandatory for password reinitialisation
  Activate Lien envoyé par e-mail
• Rules

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
  match /doleances/{entry} {
      allow read: if true;
      allow write: if (request.auth.uid == 'iQR5zG3KR2NnNTwjp9KFgaoShTF2'
      || request.auth.uid == 'U4W9t7rYlnbLso1fZvdxUe2qQol2');
    }
    match /configuration/{entry} {
      allow read: if true;
      allow write: if (request.auth != null
      && request.auth.uid == 'U4W9t7rYlnbLso1fZvdxUe2qQol2');
    }
    match /fcmTokens/{token} {
      allow read: if false;
      allow write;
    }
  }
}

##4. Configure Firebase web ###4.1 Edit web/index.html

• Add Firebase config retrieved from https://console.firebase.google.com/?hl=fr

<body>
//...
<script src="https://www.gstatic.com/firebasejs/8.6.1/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/8.6.1/firebase-auth.js"></script>
<script src="https://www.gstatic.com/firebasejs/8.6.1/firebase-firestore.js"></script>
<script src="https://www.gstatic.com/firebasejs/8.10.0/firebase-analytics.js"></script>
<script type="module">
  import { initializeApp } from "https://www.gstatic.com/firebasejs/9.0.1/firebase-app.js";
  const firebaseConfig = {
      //... Here add config
  };
  // Initialize Firebase
  firebase.initializeApp(firebaseConfig);
</script>
</body>

##5. Configure hosting Minimal configuration

flutter build web --release
firebase init // check with space : hosting 
firebase deploy

% firebase init
? Which Firebase features do you want to set up for this directory?
Hosting: Configure files for Firebase Hosting and (optionally) set up GitHub Action deploys
? What do you want to use as your public directory? build/web
Configure as a single-page app? y
File build/web/index.html already exists. Overwrite? N
i Skipping write of build/web/index.html
i Writing configuration info to firebase.json...
i Writing project information to .firebaserc...
% firebase deploy
