App Inbox

Add a message inbox to your app using the Flutter SDK

The App Inbox feature adds a mobile communication channel directly in the app. The App Inbox can receive messages sent by campaigns and store mobile push notifications for a defined period. Note that the SDK can only fetch App Inbox messages if the current app user has a customer profile identified by a hard ID.

Refer to the App Inbox documentation for information on creating and sending App Inbox messages in the Engagement web app.

👍
App Inbox is a separate module that can be enabled on request in your Engagement account by your Bloomreach CSM.

Integrate the App Inbox

You can integrate the App Inbox through a button provided by the SDK, which opens the App Inbox messages list view.

You can then add the button anywhere in your app. For example:

ListTile(
  title: const Text('App Inbox'),
  subtitle: Row(
    children: const [
      SizedBox(width: 150, height: 50, child: AppInboxProvider()),
    ]
  )
),

The App Inbox button registers a click action to show an App Inbox list screen.

That's all that's required to integrate the App Inbox. Optionally, you can customize it to your needs.

See home.dart for a reference implementation.

Default App Inbox Behavior

The SDK fetches and displays the App Inbox automatically as follows:

Display a button to access the App Inbox messages list view (integration by developer).
Display a messages list view. Display each item with:
- Flag indicating whether the message is read or unread.
- Delivery time in human-readable form (for example, 2 hours ago).
- Single-lined title of the message (ended by '...' for longer values).
- Two-lined content of the message (ended by '...' for longer values).
- Squared image if the message contains any.
- Loading progress indicator of the list.
- Empty Inbox title and message in case there are no messages.
- Error title and description in case of an error loading the list
Call ExponeaPlugin().trackAppInboxOpened when the user clicks on a list item and mark the message as read automatically.
Display a message detail view that contains:
- Large squared image (or a gray placeholder if the message doesn't contain an image).
- Delivery time in human-readable form (for example, 2 hours ago).
- Full title of the message.
- Full content of the message.
- A button for each action in the message that opens a browser link or invokes a universal link. No button is displayed for an action that opens the current app.
Call ExponeaPlugin().trackAppInboxClick automatically when the user clicks a button in the message detail view.

App Inbox messages list view and message detail view

❗️
Note that the SDK can only fetch App Inbox messages if the current app user has a customer profile identified by a hard ID.

❗️
The behavior of trackAppInboxOpened and trackAppInboxClick may be affected by the tracking consent feature, which in enabled mode considers the requirement of explicit consent for tracking. Refer to Consent for details.

Customize App Inbox

Although the App Inbox works out of the box once the button has been integrated in your app, you may want to customize it to your app's requirements.

Localization

The SDK provides the following UI labels in English. You can modify these or add localized labels by defining customized strings.

For Android, add to your strings.xml files:

<string name="exponea_inbox_button">Inbox</string>
<string name="exponea_inbox_title">Inbox</string>
<string name="exponea_inbox_defaultTitle">Inbox message</string>
<string name="exponea_inbox_emptyTitle">Empty Inbox</string>
<string name="exponea_inbox_emptyMessage">You have no messages yet.</string>
<string name="exponea_inbox_errorTitle">Something went wrong :(</string>
<string name="exponea_inbox_errorMessage">We could not retrieve your messages.</string>
<string name="exponea_inbox_mainActionTitle">See more</string>

For iOS, add to your Localizable.string files:

"exponea.inbox.button" = "Inbox";
"exponea.inbox.title" = "AppInbox";
"exponea.inbox.loading" = "Loading messages...";
"exponea.inbox.emptyTitle" = "Empty Inbox";
"exponea.inbox.emptyMessage" = "You have no messages yet.";
"exponea.inbox.errorTitle" = "Something went wrong :(";
"exponea.inbox.errorMessage" = "We could not retrieve your messages.";
"exponea.inbox.defaultTitle" = "Message";
"exponea.inbox.mainActionTitle" = "See more";

Customize UI Styles

The App Inbox screens are designed to satisfy most customers' needs. However, they may not fit the design of your application. You can customize colors and text styles through configuration.

_plugin.setAppInboxProvider(AppInboxStyle(
      appInboxButton: SimpleButtonStyle(
        // ButtonStyle
        textOverride: 'text value',
        textColor: 'color',
        backgroundColor: 'color',
        showIcon: true,
        textSize: '12px',
        enabled: true,
        borderRadius: '5px',
        textWeight: 'bold|normal|100..900'
      ),
      detailView: DetailViewStyle(
        title: TextViewStyle(
          // TextViewStyle
          visible: true,
          textColor: 'color',
          textSize: '12px',
          textWeight: 'bold|normal|100..900',
          textOverride: 'text'
        ),
        content: TextViewStyle(...),
        receivedTime: TextViewStyle(...),
        image: ImageViewStyle(
          // ImageViewStyle
          visible: true,
          backgroundColor: 'color'
        ),
        button: SimpleButtonStyle(),
      },
      listView: ListScreenStyle(
        emptyTitle: TextViewStyle(...),
        emptyMessage: TextViewStyle(...),
        errorTitle: TextViewStyle(...),
        errorMessage: TextViewStyle(...),
        progress: ProgressBarStyle(
          // ProgressBarStyle
          visible: true,
          progressColor: 'color',
          backgroundColor: 'color'
        ),
        list: AppInboxListViewStyle(
          backgroundColor: 'color',
          item: AppInboxListItemStyle(
            backgroundColor: 'color',
            readFlag: ImageViewStyle(),
            receivedTime: TextViewStyle(...),
            title: TextViewStyle(...),
            content: TextViewStyle(...),
            image: ImageViewStyle(),
          ),
        ),
      )
    })

Supported colors formats:

Short hex #rgb or with alpha #rgba
Hex format #rrggbb or #rrggbbaa
RGB format rgb(255, 255, 255)
RGBA format rgba(255, 255, 255, 1.0) or rgba(255 255 255 / 1.0)
ARGB format argb(1.0, 255, 255, 255)
Name format yellow (names has to be supported by Android/iOS platform)

Supported size formats:

Pixels 12px or 12
Scaleable Pixels 12sp
Density-independent Pixels 12dp or 12dip
Points 12pt
Inches 12in

❗️
The iOS platform does not support DPI conversions and only accepts number values for size.

Supported text weight formats:

'normal' - normal/regular style on both platforms
'bold' - bold style on both platforms
Number from 100 to 900 - mainly usable on iOS. Limited support on Android (100-600 means 'normal'; 700-900 means 'bold')

👍
You may register your own styling at any time - before SDK initialization or later in some of your screens. Every action in scope of the App Inbox uses currently registered styles. We recommend to register your styles configuration right before you initialize the SDK.

App Inbox Data API

The SDK provides methods to access App Inbox data directly without accessing the UI layer.

Fetch App Inbox

The App Inbox is assigned to an existing customer account (identified by a hard ID). Calling either of the following methods will clear the App Inbox:

ExponeaPlugin().identifyCustomer
ExponeaPlugin().anonymize

To prevent large data transfers on each fetch, the SDK stores the App Inbox locally and loads incrementally. The first fetch will transfer the entire App Inbox, but subsequent fetches will only transfer new messages.

The App Inbox assigned to the current customer can be fetched as follows:

var messages = await ExponeaPlugin().fetchAppInbox();

It's also possible to fetch a single message by its ID from the App Inbox as follows:

var message = await ExponeaPlugin().fetchAppInboxItem(messageId);

Fetching a single message triggers fetching the entire App Inbox (including incremental loading) but will retrieve the data from local storage if the App Inbox was fetched previously.

Mark Message as Read

Use the markAppInboxAsRead method, passing an App Inbox message object as argument, to mark the message as read:

var markedAsRead = ExponeaPlugin().markAppInboxAsRead(message);

❗️
Marking a message as read using the markAppInboxAsRead method does not trigger a tracking event for opening the message. To track an opened message, you need to call the ExponeaPlugin().trackAppInboxOpened method).

Track App Inbox Events Manually

The SDK tracks App Inbox events automatically by default. In case of a custom implementation, it is the developers' responsibility to use the relevant tracking methods in the right places.

Track Opened App Inbox Message

Use the ExponeaPlugin().trackAppInboxOpened(MessageItem) method to track the opening of App Inbox messages.

The behavior of trackAppInboxOpened may be affected by the tracking consent feature, which, when enabled, requires explicit consent for tracking. Refer to Tracking Consent for details.

If you want to ignore tracking consent, use ExponeaPlugin().trackAppInboxOpenedWithoutTrackingConsent instead. This method will track the event regardless of consent.

Track Clicked App Inbox Message Action

Use the ExponeaPlugin().trackAppInboxClick(MessageItemAction, MessageItem) method to track action invocations in App Inbox messages.

The behavior of trackAppInboxClick may be affected by the tracking consent feature, which, when enabled, requires explicit consent for tracking. Refer to Tracking Consent for details.

If you want to ignore tracking consent, use ExponeaPlugin().trackAppInboxClickWithoutTrackingConsent instead. This method will track the event regardless of consent.
