Today you will learn how you can easily change the Android minSdkVersion in Flutter for both (Before 2.8 Update and After Flutter 2.8 Update) versions.

Step 1: Find local.properties Folder

project_folder/android/local.properties

Step 2: Add the following lines

flutter.minSdkVersion=21

Step 3: Open build.gradle file

project_folder/android/app/build.gradle

Step 4: Update minsdkVersion inside defaultConfig section

localProperties.getProperty(‘flutter.minSdkVersion’).toInteger()

Step 5: Clean the flutter project

Inside the terminal, run the flutter clean command.

flutter clean

Step 6: Re build you app.

Your Android minSdkVersion will be changed.

Example:

local.properties

sdk.dir=/Users/HussainHumdani/Library/Android/sdk
flutter.sdk=/Users/HussainHumdani/development/flutter
flutter.minSdkVersion=21 #here you add the minSdkVersion

build.gradle File (android/app/build.gradle)

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.cwh2"
        // You can update the following values to match your application needs.
        // For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-build-configuration.
        // minSdkVersion flutter.minSdkVersion        Old Line
        minSdkVersion localProperties.getProperty('flutter.minSdkVersion').toInteger() //New Line
        targetSdkVersion flutter.targetSdkVersion
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

Project Created Before 2.8 Update

Step 1: Go to the build.gradle file

project_folder/android/app/build.gradle

Step 2: Find defaultConfig and update minSdkVersion

defaultConfig {
    applicationId "com.example.cwh"
    minSdkVersion 21 // This is the value that you update
    targetSdkVersion 30
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
}
