This guide details how to customize the `MessageWidget` in the Stream Chat Flutter UI SDK. ### Theming You can customize the `MessageWidget` using the `StreamChatTheme` class, so that you can change the message theme at the top instead of creating your own `MessageWidget` at the lower implementation level. There are several things you can change in the theme including text styles and colors of various elements. You can also set a different theme for the user's own messages and messages received by them. Here is an example: ```dart StreamChatThemeData( /// Sets theme for user's messages ownMessageTheme: MessageThemeData( messageBackgroundColor: colorTheme.textHighEmphasis, ), /// Sets theme for received messages otherMessageTheme: MessageThemeData( avatarTheme: AvatarThemeData( borderRadius: BorderRadius.circular(8), ), ), ) ``` #### Change message text style The `MessageWidget` has multiple `Text` widgets that you can manipulate the styles of. The three main are the actual message text, user name, message links, and the message timestamp. ```dart MessageThemeData( messageTextStyle: TextStyle(...), createdAtStyle: TextStyle(...), messageAuthorStyle: TextStyle(...), messageLinksStyle: TextStyle(...), ) ``` #### Change avatar theme You can change the attributes of the avatar (if displayed) using the `avatarTheme` property.
