Answer 1

For Android

Goto, app level build.gradle and specify your unique applicationID

    defaultConfig {
    applicationId "your-package-name"
    minSdkVersion 16
    targetSdkVersion 27
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    multiDexEnabled true
}

For IOS

Goto, Info.plist inside ios/Runner directory and change the bundler identifier

<key>CFBundleIdentifier</key>
<string>com.your.packagename</string>

This is a quick way of getting it done using project level find and replace. Click CTRL + SHift + R Then type the name of the old package name com.old.package_name, this will show you everywhere the old package name is used in the project. Then type the name of the new package name you want to replace it with in the lower tab: com.new.package_name then click replace all. This worked for me.
