Flutter Configuration

LovinaChatConfig

The LovinaChatConfig class holds all configuration options for the chat widget.

final config = LovinaChatConfig(
  websiteToken: 'your-website-token',
  baseUrl: 'https://chat-prod.ailovina.com',
  locale: 'en',
  colorScheme: 'auto',
  user: null,
  theme: null,
  branding: null,
  texts: null,
  features: null,
  displayMode: 'fullscreen',
);

Fields

Parameter	Type	Default	Required	Description
websiteToken	String	--	Yes	Your Lovina website token for this agent. Obtained from the Lovina dashboard -- each agent has its own token.
baseUrl	String	--	Yes	Base URL of your Lovina instance (e.g., https://chat-prod.ailovina.com).
locale	String	'id'	No	Widget locale code. Supported values include 'id', 'en', 'ar'.
colorScheme	String	'auto'	No	Dark mode preference for the widget. Accepts 'light', 'dark', or 'auto' (follows system theme).
user	LovinaChatUser?	null	No	Pre-identified user to associate with the conversation. See below.
theme	LovinaThemeConfig?	null	No	Theme color, typography, and sizing overrides. Only primaryColor is required in practice -- see Theming.

texts	Map<String, dynamic>?	null	No	UI string overrides, keyed by translation key.
features	LovinaFeatureFlags?	null	No	Feature-flag overrides.

hideKeyboardAccessoryBar	bool	true	No	Suppress WebKit's keyboard form-assistant bar on iOS while the chat widget is visible. See iOS Keyboard Accessory Bar below.

Theming

Only LovinaThemeConfig.primaryColor is required in practice -- every other color is auto-generated by the widget to meet WCAG AA contrast:

LovinaChatConfig(
  websiteToken: 'your-website-token',
  baseUrl: 'https://chat-prod.ailovina.com',
  theme: LovinaThemeConfig(
    primaryColor: '#6366F1',
    fontFamily: 'Inter, sans-serif',
    bubbleRadius: 16,
  ),
  branding: LovinaBrandingConfig(
    brandName: 'Acme Support',
    poweredBy: false,
  ),
);

LovinaChatUser

The LovinaChatUser class represents a pre-identified user.

Parameter	Type	Required	Description
identifier	String	Yes	Unique user ID in your system.
name	String?	No	Display name.
email	String?	No	Email address.
avatarUrl	String?	No	Avatar image URL.
identifierHash	String?	No	HMAC hash for identity verification. Generate server-side.
phoneNumber	String?	No	Phone number (E.164 format recommended).
customAttributes	Map<String, dynamic>?	No	Arbitrary key-value metadata attached to the contact.

Event Types

All events extend the ChatEvent base class.

Event Class	Properties	Description
ChatLoadedEvent	authToken (String?)	Widget finished loading.
MessageReceivedEvent	message (Map<String, dynamic>)	New message received.
UnreadCountChangedEvent	count (int)	Unread count changed.
ChatClosedEvent	reason (String?)	Chat was closed.
ChatErrorEvent	code (String), message (String)	An error occurred.

iOS Keyboard Accessory Bar

hideKeyboardAccessoryBar (default true) suppresses WebKit's keyboard form-assistant bar (Previous/Next/Done) while the chat widget's WebView has focus.

Note: this suppresses the accessory bar for any WebView in your app while the chat is mounted, not just the chat's own. If your app has other WebViews (e.g. an in-app browser), set hideKeyboardAccessoryBar: false to avoid affecting them.
