push_notification

A new Flutter project.

App configuration for firebase push notification:

• Create firebase Project for individual project

• set up and change (optional) package name : The package name will be available in the ./android/app/build.gradle file of your Flutter project.

• After register: google-services.json file which will link our Flutter app to Firebase Google services. We need to download the file and move it to the ./android/app directory of our Flutter project.

• Add Firebase Configurations to Native Files in your Flutter Project: root-level (project-level) Gradle file (android/build.gradle), we need to add rules to include the Google Services Gradle plugin.

buildscript {
    repositories {
        // Check that you have the following line (if not, add it):
        google()  // Google's Maven repository
    }
    dependencies {
    ...
        // Add this line
        classpath 'com.google.gms:google-services:4.3.4'
    }
    }
    allprojects {
        ...
        repositories {
        // Check that you have the following line (if not, add it):
        google()  // Google's Maven repository
        ...
    }
}

• (app-level) Gradle file (android/app/build.gradle), we need to apply the Google Services Gradle plugin.

// Add the following line:
  **apply plugin: 'com.google.gms.google-services'**  // Google Services plugin

• Integrate Firebase Messaging with Flutter: add the firebase-messaging dependency to the ./android/app/build.gardle file.

dependencies {
    //add this line
    implementation platform('com.google.firebase:firebase-bom:32.1.0')
    implementation 'com.google.firebase:firebase-analytics-ktx'
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
}
root level build.gradle
    dependencies {
    //add this
    classpath 'com.google.gms:google-services:4.3.15'
}
