But now I'am stuck at an error which I cannot handle. I coded a function which is supposed to asynchronously return the actual BTC price from https://blockchain.info/ticker.

                                                                                  .myMaxHeightClass {

                                                                                  This should make the content full screen and your footer will stay sticky at the bottom.

                                                                                  Avoid using absolute positioned footer buttons, as in my experience leads to a big mess.

                                                                                  Let me know if this works for you and if it doesn't, I will try to come up with a different approach

                                                                                  Asked 2022-Feb-06 at 09:48

                                                                                  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:

                                                                                  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).

But as soon as a message gets to 2+ lines it struggles to scroll to the bare bottom. The more rows of a message the less it scrolls to the bottom.

                                                                                  This is how it looks like when i enter the chat:

                                                                                  But if i scroll down further this is the bottom of the chat:

                                                                                  I noticed there's also a case when:

                                                                                  1. I enter the chat.
                                                                                  2. It scrolls down like on the first image.
                                                                                  3. If i tap anywhere on the screen, it continues to scroll to the bare bottom of the listview like on the second image.

                                                                                  Why does this happen and how do i fix this?

                                                                                  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.

                                                                                  Portrait mode

                                                                                  Additionally some items have a separate property, TextAlign, which sets the position for a text within the space of the Align result.

                                                                                  Does anyone know how to implement this using the same package or can hint me to an example.

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)
