Type 'FixedScrollMetrics' is not a subtype of type 'PageMetrics'

[agustincards14]

Hello,

This seems to be a problem when using a scroll view (ListView in my case) as a PageView child and scrolling vertically (or perpendicular) to the PageView orientation.

Below is the stack trace: I/flutter ( 4144): ══╡ EXCEPTION CAUGHT BY GESTURE ╞═══════════════════════════════════════════════════════════════════ I/flutter ( 4144): The following _TypeError was thrown while handling a gesture: I/flutter ( 4144): type 'FixedScrollMetrics' is not a subtype of type 'PageMetrics' I/flutter ( 4144): I/flutter ( 4144): When the exception was thrown, this was the stack: I/flutter ( 4144): #0 PageContainerState._onScroll (package:page_indicator/src/container.dart:114:25) I/flutter ( 4144): #1 NotificationListener._dispatch (package:flutter/src/widgets/notification_listener.dart:129:41) I/flutter ( 4144): #2 Notification.visitAncestor (package:flutter/src/widgets/notification_listener.dart:47:20) I/flutter ( 4144): #3 ViewportNotificationMixin.visitAncestor (package:flutter/src/widgets/scroll_notification.dart:31:18) I/flutter ( 4144): #4 Element.visitAncestorElements (package:flutter/src/widgets/framework.dart:3989:39) I/flutter ( 4144): #5 Notification.dispatch (package:flutter/src/widgets/notification_listener.dart:63:13) I/flutter ( 4144): #6 DragScrollActivity.dispatchScrollUpdateNotification (package:flutter/src/widgets/scroll_activity.dart:443:139) I/flutter ( 4144): #7 ScrollPosition.didUpdateScrollPositionBy (package:flutter/src/widgets/scroll_position.dart:721:14) I/flutter ( 4144): #8 ScrollPosition.setPixels (package:flutter/src/widgets/scroll_position.dart:245:9) I/flutter ( 4144): #9 ScrollPositionWithSingleContext.setPixels (package:flutter/src/widgets/scroll_position_with_single_context.dart:83:18) I/flutter ( 4144): #10 ScrollPositionWithSingleContext.applyUserOffset (package:flutter/src/widgets/scroll_position_with_single_context.dart:126:5) I/flutter ( 4144): #11 ScrollDragController.update (package:flutter/src/widgets/scroll_activity.dart:372:14) I/flutter ( 4144): #12 ScrollableState._handleDragUpdate (package:flutter/src/widgets/scrollable.dart:543:12) I/flutter ( 4144): #13 DragGestureRecognizer._checkUpdate.<anonymous closure> (package:flutter/src/gestures/monodrag.dart:403:54) I/flutter ( 4144): #14 GestureRecognizer.invokeCallback (package:flutter/src/gestures/recognizer.dart:182:24) I/flutter ( 4144): #15 DragGestureRecognizer._checkUpdate (package:flutter/src/gestures/monodrag.dart:403:7) I/flutter ( 4144): #16 DragGestureRecognizer.handleEvent (package:flutter/src/gestures/monodrag.dart:258:9) I/flutter ( 4144): #17 PointerRouter._dispatch (package:flutter/src/gestures/pointer_router.dart:76:12) I/flutter ( 4144): #18 PointerRouter._dispatchEventToRoutes.<anonymous closure> (package:flutter/src/gestures/pointer_router.dart:122:9) I/flutter ( 4144): #19 _LinkedHashMapMixin.forEach (dart:collection-patch/compact_hash.dart:379:8) I/flutter ( 4144): #20 PointerRouter._dispatchEventToRoutes (package:flutter/src/gestures/pointer_router.dart:120:18) I/flutter ( 4144): #21 PointerRouter.route (package:flutter/src/gestures/pointer_router.dart:106:7) I/flutter ( 4144): #22 GestureBinding.handleEvent (package:flutter/src/gestures/binding.dart:218:19) I/flutter ( 4144): #23 GestureBinding.dispatchEvent (package:flutter/src/gestures/binding.dart:198:22) I/flutter ( 4144): #24 GestureBinding._handlePointerEvent (package:flutter/src/gestures/binding.dart:156:7) I/flutter ( 4144): #25 GestureBinding._flushPointerEventQueue (package:flutter/src/gestures/binding.dart:102:7) I/flutter ( 4144): #26 GestureBinding._handlePointerDataPacket (package:flutter/src/gestures/binding.dart:86:7) I/flutter ( 4144): #30 _invoke1 (dart:ui/hooks.dart:275:10) I/flutter ( 4144): #31 _dispatchPointerDataPacket (dart:ui/hooks.dart:184:5) I/flutter ( 4144): (elided 3 frames from dart:async) I/flutter ( 4144): I/flutter ( 4144): Handler: "onUpdate" I/flutter ( 4144): Recognizer: I/flutter ( 4144): VerticalDragGestureRecognizer#89b5b
