QUESTION
I'm building an app where I have a page which gives information about a specific trading card. I want the page to be scrollable, but I also want to have a grid on the page, with each grid cell showing one data point. I made the grid using GridView.count().
My problem is that instead of have a page which I can scroll through, the top half of the page stays static, while the grid is scrollable. How do I make the grid static, while the rest of the page scrollable? I intend to have more data below this grid as well, and I want to user to be able to scroll to see all of it, with the grid being a static component of the page.
Here's my code:
...ANSWER
Answered 2022-Feb-06 at 09:47You can provide physics: NeverScrollableScrollPhysics() on GridView to disable scroll effect. If you want scrollable as secondary widget use primary: false,
To have Full Page scrollable, you can use body:SingleChildScrollView(..) or better using body:CustomScrollView(..)
QUESTION
I am posting this question to help future readers. After upgrading to Flutter 2.8 I suddenly got this error when trying to run my app:
ANSWER
Answered 2021-Dec-26 at 14:20Turns out this error was caused by a popular library I used (settings_ui) that does not work with this version of Flutter (settings_ui: ^1.0.0).
For future readers: Use a later version of this package. There is currently an open issue on github that addresses this.
Update 2022: Dev on settings_ui seems to have gone AWOL and no longer merging PR's the community has forked this project to: https://pub.dev/packages/flutter_settings_ui and here updates are properly merged and a fix has been released in version 1.0.1
For people facing this issue now:
As a monkey patch you can follow the steps in the GitHub issue and edit the package files locally:
In cupertino_settings_item.dart
change final ListTileTheme tileTheme = ListTileTheme.of(context); to final tileTheme = ListTileTheme.of(context);
And change _iconColor(ThemeData theme, ListTileTheme tileTheme) to _iconColor(ThemeData theme, ListTileThemeData tileTheme).

QUESTION
I am fairly new to the Firemonkey framework after working with VCL for many years so hopefully this question is not too simple.
I am listing Dynamic Listview Items which I update from a database. I have created the position/layout of the text within the Listview Item using design mode . My question is when I change screen orientation from portrait to landscape do I have to manually change the 'X' position of the text items located within my listview and their width so that the full landscape width of the screen is utilized? There appears to be no anchors for dynamically created Listview items. (The text items just have their generic names for the time being.)
I have a pic below of what I am trying to describe. First pic shows deign mode in portrait and second in landscape.
Any suggestions greatly appreciated.
...ANSWER
Answered 2021-Dec-22 at 23:30The Accessory, Detail and Text items have an Align property that can take values Center, Leading or Trailing. They are recalculated and adjust their position with changes in the screen orientation.
Additionally some items have a separate property, TextAlign, which sets the position for a text within the space of the Align result.

QUESTION
I have a mobile application developed using Ionic. Now I want to redevelop it in flutter and publish a new update, would that be possible? will google play and AppStore allow that?
...ANSWER
Answered 2021-Dec-17 at 19:07There is no constraint on development language. But,
- You need to use same certificates/keys for iOS App
- You need to use same key-store/keys for Android App
- If you are using local database or file storage, then you should follow the same path in your newly created app as well. If you are using any third-party library to manage the db or file paths, then it may be in different location altogether. (This one actually happened to me. When I migrated my app from a cross-platform framework to Native the database path got changed in release version)
