Delve into Flutter's UI framework to build high-quality Android apps, from creating contact profiles to enhancing them with themes and API integration, culminating in app publication.

Flutter is Google’s mobile UI framework used for crafting high-quality native interfaces on iOS and Android. This course focuses on building applications for the Android platform.

You’ll start by exploring the intricacies of Flutter and work your way up to implementing a contact profile page for an Android address book.

In the latter half of the course, you’ll learn to work with Flutter themes to spruce up the contact profile app you created. To round out your Flutter experience, you’ll also practice fetching data from a remote Application Programming Interface (API).

You’ll put into practice what you learn using live coding environments embedded within the course. By the time you’re done, you’ll be ready to create your own Android app and publish it to the Google Play Store.

Beginning Flutter: Android Mobile App Development

# Introduction to Local theme
The local theme is responsible for making changes to one part of the app without affecting any other part of the app. 

Local themes are implemented using the [`Theme`](https://api.flutter.dev/flutter/material/Theme-class.html) widget and passing specific `ThemeData` instances to it. 


In this lesson, we’ll create a local theme for the *Profile Page's* widget consisting of action items: "Call," "Text," "Video," "Email," "Directions," and "Pay" as mentioned in the [previous chapter](https://www.educative.io/courses/beginning-flutter-android-mobile-app-development/profile-actions-items).


The local theme helps to define a theme for a smaller part of the app.

The `Theme` widget is used to assign local themes to different material app widgets.

Let’s take a look at the part of the app that builds profile action items:
```
Container(
    margin: const EdgeInsets.only(top: 8, bottom: 8),
    //Builds custom widget for actions items  
    child: profileActionItems(),
),
 
```
Now, to assign a different color for action item icons, we can use a local theme.

Local themes are defined as `data` property of the `Theme` widget, like below:

```
Theme(
 data: ThemeData(
   //Assigning color for icons
   iconTheme: IconThemeData(
     color: Colors.pink,
   ),
 ),
)
```

Imagine, you want your profile action item icons to be of ‘Colors.pink’ regardless of the theme of the app. 

In that case, you can use a local theme by wrapping `profileActionItems()` as a child to the `Theme` widget.

```
Container(
    margin: const EdgeInsets.only(top: 8, bottom: 8),
    //Defining Theme for it's child widget
    child: Theme(
         data: ThemeData(
         iconTheme: IconThemeData(
         color: Colors.pink,
         ),
        ),
         //This widget applies iconTheme defined above. All icons will be pink for this widget.
        child: profileActionItems(),
   ),
),
 
```

In this lesson, you'll learn how to use Local theme in the Flutter app.
