How to solve Multidexing problem in Android

            Steps to remove multidexing Problem in Android

What is multidex file and why we need for the APK file?
Android application (APK) files contain executable bytecode files in the form of Dalvik Executable (DEX) files, which contain the compiled code used to run your app. The Dalvik Executable specification limits the total number of methods that can be referenced within a single DEX file to 65,536, including Android framework methods, library methods, and methods in your own code. Getting past this limit requires that you configure your app build process to generate more than one DEX file, known as a multidex configuration.
How to configure our application for multidex?

1. Add  dependency in your app build.gradle(Module:app) and Click on  Sync


 If your API Level is 20 or less than 20 you need  to add support library








    dependencies {


        compile 'com.android.support:multidex:1.0.1'       


 }




  But If your API Level is 21 or more than 21 you do not need  to add support library






2. Insert this line of code in your  build.gradle(Module level) file 




       android {
        defaultConfig {
        minSdkVersion 21      


        targetSdkVersion 26       


        multiDexEnabled true        


               }


           }


3.Then you add this line in  Manifest file


    android:name="android.support.multidex.MultiDexApplication"




 Example:


  <application


    android:allowBackup="true"  


    android:icon="@mipmap/ic_launcher" 


    android:label="@string/app_name"  


    android:supportsRtl="true"  


    android:theme="@style/AppTheme"  


    android:name="android.support.multidex.MultiDexApplication">


4. Create a java file and extends MultiDexApplication in it and install mutidex in it


Example:


public class Myapplication extends MultiDexApplication {


    @Override    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
    }


5.  Click on Sync project

Expected a key while parsing a block mapping (Flutter)




























  Flutter makes use of the Dart packaging system, pub. Via your applications  pubspec.yam l file (or simple pubspec), you can pull down packages from the flutter ecosystem, or the broader dart community.   Anyway, i need to add some images to my flutter application, and so had to add an assets section to the pubspec .the default Android Studio generated apps  pubspec  has a lot of commented out code with explainations about what is going on, e.g  # To add assets to your application, add an assets section, like this: # assets:   # - images/a_dot_burr.jpeg   # - images/a_dot_ham.jpeg # An image asset can refer to one or more resolution-specific "variants", see  # https://flutter.io/assets-and-images/#resolution-aware.    So I uncommented these lines   # assest :  -  -  -  #  -  images/a_dot_ham.jpeg   with the idea from these comment.  that i would just edit it to suit my particular needs. Once you have edited your  pubspec, you need to click on the "Get dependenc...
