This is a known limitation + * with React Native Gesture Handler on Android when multiple gesture root views exist in overlays. + * + * **Current Behavior:** + * - iOS: Top and bottom banners work correctly together with independent gesture handling + * - Android: If both top and bottom banners appear simultaneously, gestures may not work on one section + * + * **Workaround (Not Yet Implemented):** + * To fully support Android, the implementation should: + * 1. Detect when both top and bottom banners exist on Android + * 2. Prioritize showing banners from one position (e.g., top takes precedence) + * 3. Queue banners from the other position until the primary position is clear + * + * **Previous iOS-Only Solution:** + * The implementation creates TWO separate GestureHandlerRootView instances - one for top + * banners and one for bottom banners. Each is positioned and sized only for its banner content + * using `useBannerGestureRootPosition` hook. On iOS this allows: + * - Top and bottom banners to coexist without blocking the middle of the screen + * - User interactions with app content between the banners + * - Each banner section to handle gestures independently + * - `pointerEvents='box-none'` on each GestureHandlerRootView allows touches to pass through + * non-banner areas to the content underneath + * + * @example + * // Show a simple banner + * BannerManager.showBanner({ + * id: 'network-error', + * title: 'Connection Lost', + * message: 'Reconnecting...', + * type: 'error', + * position: 'top' + * }); + * + * @example + * // Show multiple banners (they will stack) + * BannerManager.showBanner({id: 'banner1', position: 'top', ...}); + * BannerManager.showBanner({id: 'banner2', position: 'bottom', ...}); + * + * @example + * // Show with auto-hide + * BannerManager.showBannerWithAutoHide({ + * id: 'success', + * message: 'Changes saved', + * type: 'success' + * }, 3000); + */ +class BannerManagerSingleton { + private activeBanners: FloatingBannerConfig[] = []; + private overlayVisible = false; + private autoHideTimers: Map = new Map(); + private updateQueue: Promise = Promise.resolve(); + private dismissOverlayTimer: NodeJS.Timeout | null = null; + private dismissOverlayResolve: (() => void) | null = null; + + private clearBannerTimer(bannerId: string) { + const timer = this.autoHideTimers.get(bannerId); + if (timer) { + clearTimeout(timer); + this.autoHideTimers.delete(bannerId); + } + } + + private clearAllTimers() { + this.autoHideTimers.forEach((timer) => clearTimeout(timer)); + this.autoHideTimers.clear(); + } + + private cancelDismissOverlay() { + if (this.dismissOverlayTimer) { + clearTimeout(this.dismissOverlayTimer); + this.dismissOverlayTimer = null; + } + + // Resolve the pending Promise to unblock the queue + if (this.dismissOverlayResolve) { + this.dismissOverlayResolve(); + this.dismissOverlayResolve = null; + } + } + + private removeBannerFromList(bannerId: string) { + const bannerIndex = this.activeBanners.findIndex((b) => b.id === bannerId); + if (bannerIndex >= 0) { + const banner = this.activeBanners[bannerIndex]; + this.activeBanners.splice(bannerIndex, 1); + + // Clear any auto-hide timer for this banner + this.clearBannerTimer(bannerId); + + // Invoke onDismiss callback if it exists + if (banner.onDismiss) { + try { + banner.onDismiss(); + } catch { + // Silent catch to ensure cleanup still runs + } + } + } + } + + private updateOverlay() { + this.updateQueue = this.updateQueue.then(async () => { + if (!this.activeBanners.length) { + if (this.overlayVisible) { + Navigation.updateProps(FLOATING_BANNER_OVERLAY_ID, { + banners: [], + onDismiss: () => { + // No-op: no banners to dismiss + }, + }); + + await new Promise((resolve) => { + this.dismissOverlayResolve = resolve; + this.dismissOverlayTimer = setTimeout(() => { + this.dismissOverlayResolve = null; + resolve(); + }, OVERLAY_DISMISS_DELAY); + }); + + if (!this.activeBanners.length && this.overlayVisible) { + await dismissOverlay(FLOATING_BANNER_OVERLAY_ID); + this.overlayVisible = false; + } + this.dismissOverlayTimer = null; + } + return; + } + + this.cancelDismissOverlay(); + + const handleDismiss = (id: string) => { + this.removeBannerFromList(id); + this.updateOverlay(); + }; + + const bannersWithDismissProps = this.activeBanners.map((banner) => { + if (banner.customComponent && React.isValidElement(banner.customComponent)) { + const props: Partial> = { + onDismiss: () => handleDismiss(banner.id), + dismissible: banner.dismissible, + }; + return { + ...banner, + customComponent: React.cloneElement(banner.customComponent, props), + }; + } + return banner; + }); + + if (this.overlayVisible) { + Navigation.updateProps(FLOATING_BANNER_OVERLAY_ID, { + banners: bannersWithDismissProps, + onDismiss: handleDismiss, + }); + } else { + showOverlay( + Screens.FLOATING_BANNER, + { + banners: bannersWithDismissProps, + onDismiss: handleDismiss, + }, + { + overlay: { + interceptTouchOutside: false, + }, + }, + FLOATING_BANNER_OVERLAY_ID, + ); + this.overlayVisible = true; + } + }); + } + + showBanner(bannerConfig: FloatingBannerConfig) { + this.removeBannerFromList(bannerConfig.id); + + this.activeBanners.push(bannerConfig); + + this.updateOverlay(); + } + + showBannerWithAutoHide(bannerConfig: FloatingBannerConfig, durationMs: number = BANNER_DEFAULT_TIME_TO_HIDE) { + this.showBanner(bannerConfig); + + const timer = setTimeout(() => { + this.hideBanner(bannerConfig.id); + }, durationMs); + + this.autoHideTimers.set(bannerConfig.id, timer); + } + + /** + * Hides a specific banner by ID. + * + * @param bannerId - Required banner ID to hide.

FloatingBanner Component + +**Purpose**: Main rendering component that splits banners by position and delegates to BannerSection + +```mermaid +flowchart TD + FB[FloatingBanner] --> CHECK{Banners exist?} + CHECK -->|No| NULL[Return null] + CHECK -->|Yes| SPLIT[Split by position] + + SPLIT --> TOP[Top Banners] + SPLIT --> BOTTOM[Bottom Banners] + + TOP --> BSTOP[BannerSection 'top'] + BOTTOM --> BSBOTTOM[BannerSection 'bottom'] + + BSTOP --> GHRTOP[GestureHandlerRootView

BannerSection Component + +**Purpose**: Positions and sizes the GestureHandlerRootView for a banner section (top or bottom) + +**Key Features**: +- Creates a `GestureHandlerRootView` for each section (top/bottom) +- Uses `useBannerGestureRootPosition` hook for platform-specific positioning +- Calculates container height based on number of banners +- Applies safe area insets for top banners +- Handles keyboard adjustments (iOS only) +- Returns `null` when no banners in section + +```mermaid +graph LR + subgraph "BannerSection Features" + POS["Position Calculation

Basic Banner Display + +```typescript +import {BannerManager} from '@managers/banner_manager'; + +// Simple info banner +BannerManager.showBanner({ + id: 'welcome-message', + title: 'Welcome!', + message: 'Thanks for using Mattermost', + type: 'success' +}); +``` + +### 2. Auto-hiding Banner + +```typescript +// Show banner for 3 seconds (with per-banner timer) +BannerManager.showBannerWithAutoHide({ + id: 'temp-notification', + title: 'Message Sent', + message: 'Your message was delivered successfully', + type: 'success' +}, 3000); + +// Multiple auto-hide banners work independently +BannerManager.showBannerWithAutoHide({ + id: 'banner-1', + title: 'First', + message: 'Auto-hides in 5s', + type: 'info' +}, 5000); + +BannerManager.showBannerWithAutoHide({ + id: 'banner-2', + title: 'Second', + message: 'Auto-hides in 3s', + type: 'success' +}, 3000); +// Both banners stack and auto-hide independently +``` + +### 3. Network Status Banner + +```typescript +// In NetworkConnectivityManager +private showDisconnectedBanner() { + BannerManager.showBanner({ + id: 'network-disconnected', + title: 'No Connection', + message: 'Check your internet connection', + type: 'error', + position: 'bottom', + customComponent: ( + this.handleBannerDismiss()} + /> + ) + }); +} +``` + +### 4. Custom Component Banner + +```typescript +// Custom banner with complex content +BannerManager.showBanner({ + id: 'custom-banner', + title: 'Custom', + message: 'Custom message', + customComponent: ( + + Custom banner content +
