QUESTION
I am currently designing an extension to make the notifications in the notification section of the calendar expendable. The goal is to make the noficiation expand like the initial notification on the desktop does. I have changed the type of notification added to the noficiation tray to class NotificationBanner
from class NotificationMessage
. I am currently using a work-around to make this work, this is what my expand function looks like:
ANSWER
Answered 2021-Aug-08 at 19:04Okay I have found a solution, it is not related to the layout manager. The value of the message message.bodyLabel.clutter_text.ellipsize
is set to 3, which is the main cause of the dots appearing on the notification. Setting this value to 0 solves this problem. I would have still loved to find a more elegant approach to displaying the body, but this will do.
QUESTION
While I know this may look like a duplicate with how many different posts there are about this error but I am getting this error for (which I assume) are different reasons on four different screens.
My app launches but I end up getting the Red screen error whenever I try to navigate my app because it says a widget within the screen used a Null Check operator on a null value.
Here are the errors I've gotten:
The following _CastError was thrown building NotificationBanner(dirty): Null check operator used on a null value. The relevant error-causing widget was: NotificationBanner file:///Users/alexm/carebloom-flutter/lib/Views/homeview.dart:9:7
The following _CastError was thrown building AlertBanner(dirty): Null check operator used on a null value. The relevant error-causing widget was: AlertBanner file:///Users/alexm/carebloom-flutter/lib/Views/alerts_view.dart:57:15
The following _CastError was thrown building MessageOverView(dirty): Null check operator used on a null value. The relevant error-causing widget was: MessageOverView file:///Users/alexm/carebloom-flutter/lib/widgets/navbar.dart:41:16
This one is a little different
The following _CastError was thrown building SettingsView(dirty, dependencies: [_EffectiveTickerMode], state: _SettingsViewState#ddb1e(tickers: tracking 1 ticker)): Null check operator used on a null value. The relevant error-causing widget was: SettingsView file:///Users/alexm/carebloom-flutter/lib/widgets/navbar.dart:49:16
Now I assume that the errors lie within the whatever widget came back as WidgetName(dirty). SO the code for each of those is below. However I'd like to also ask some questions on top of all this just to better my understanding and help me diagnose issues in the future. When it has WidgetName(dirty) what exactly does that mean what is (dity)? Besides the error message showing a specific widget it also gives 'The relevant error-causing widget path, is that the one I should be looking at?

Which was useful for a different error I ran into later down the line.
With this issue it ended up being something in Firebase that had an old data layout than what we were actually working with. Pretty much one of the docs from firebase was missing a field and that caused the null check operator to do its job and let me know that it received a null value.

I have the following container view:
...ANSWER
Answered 2021-Jan-25 at 22:32Look at the debug view hierarchy in Xcode and see if the view containing the button is actually showing up. You haven't set enough constraints on any of these views so the height and width look like they could be ambiguous to me. Once you're inside the view debugger, another common problem is that another invisible view is covering up the one with the button and intercepting the touch gestures.
