How to display new android progress dialog in flutter plugin?

I am building flutter plugin and try to show native progress dialog with the code below.

ProgressDialog progressDialog =new ProgressDialog(context);
progressDialog.setTitle("Downloading");
progressDialog.setMessage("Please wait while downloading map");
progressDialog.setCanceledOnTouchOutside(false);
progressDialog.show();   

And the dialog is displaying as below.

What I am expecting is default new android dialog when we create native android project like below.

What are the changes I need to do to make it work?

[Update] This is the default AndroidManifest.xml code

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.example.map_plugin">
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" />
</manifest>

I have added application tag and added several style to this but none work

<application android:theme="@android:style/Theme.Material.Light.DarkActionBar"></application>
