chicago's Issues

ScrollPaneState._handleFocusChange can call ScrollPane.of when deactivated

Splitter doesn't have the right cursor

The splitter should force the cursor to a <-> cursor while it's active (even if you pull away from the splitter).

table view row focus

the table view row raise focus on mouse down

ListView doesn't unregister its listener on the controller when it is detached

Render objects should not subscribe to anything until they are attached, and should unsubscribe from things when they are detached. RenderListView subscribes when the selectionController property is set, and never unsubscribes.

This means that if you have a ListView that uses a controller, and then you remove it from the rendering, and give the controller to something else, then when the controller changes value, that original ListView will try to dirty itself and throw an exception (because it's disposed and thus should not be mutating itself any more).

List buttons broken in Kitchen Sink demo

In the "lists" section, I can't change the Clock to the Anchor under the List Buttons header.

Clock on the down arrow.
See the menu appear.
Click on the Anchor.
Nothing happens.

Expected behavior: The menu closes and I see the Anchor displayed in the button.

Actual behavior: The menu remains open. If I click away, the Clock is still selected.

The same thing happens with the Basic and Color example List Buttons.

The text input is not rendered properly

How to localization and change font

ListViewSelectionController is too aggressive about sending notifications

ListViewSelectionController will send notifications any time any of its mutation affordances are invoked, even if the net result does not involve changing anything about the selection.

ScrollableListView.itemBuilder is not called when it changes

Hot reload should cause all the ScrollableListView children to rebuild.

When will the official version be released ?

When will the official version be released?

scrollPanel scrollbars style

Hi
is it possible to change the style of scrollbars? for example colors, radius, not displaying up and down buttons and ..??

ListViewSelectionController.isItemSelected can't be used if the ListView isn't visible

I have a list of items that can be selected or not. It affects many aspects of the app. There's a ListView that's used to configure that list of items, so I use a ListViewSelectionController as the source of truth. Unfortunately that ListView isn't always on screen, so sometimes it's not attached, and ListViewSelectionController.isItemSelected asserts that it is attached. So I can't use the ListViewSelectionController as the source of truth.

Side note: it would be great if ListViewSelectionController had an affordance to enumerate the selected items. Currently I have to just loop over the items one by one querying if they're selected, and that seems expensive given how the list is backed.

Rollup is attempting to reuse disposed layers

Since flutter/flutter#85798, Rollup is triggering the following assertion:

======== Exception caught by rendering library =====================================================
The following assertion was thrown during paint():
Attempted to create a handle to an already disposed layer: ClipRectLayer#2aefa(handles: 0, clipRect: Rect.fromLTRB(6.0, 22.0, 699.0, 242.0), clipBehavior: Clip.hardEdge).
'package:flutter/src/rendering/layer.dart':
Failed assertion: line 620 pos 7: 'layer?.debugDisposed != true'


Either the assertion indicates an error in the framework itself, or we should provide substantially more information in this error message to help you determine and fix the underlying cause.
In either case, please report this assertion by filing a bug on GitHub:

SplitPane needs minimum sizes

Right now you can shrink a pane to zero, but it really should stop shrinking beyond a specified limit.

Does not work on current stable release 2.2.0

Hi Todd,

Awesome talk and what a great library.

You might want to point out somewhere what the minimum required version of Flutter for this repo is. I did try the current latest stable (2.2.0), but then there were a lot of errors like:
../lib/src/scroll_bar.dart:826:29: Error: Type 'LongPressDownDetails' not found.

Switching to 2.3.0-1.0.pre solved it for me.

Regards,
Sander

ListButton menu goes off the bottom of the screen

When the ListButton is at the bottom of the window, it should unfold up instead of down when the menu is opened.

table view scroll performance

table view scroll slow on set view size to 1200 * 700 with 20 columns

scrolling with touchpad does not work

Any scrollable control does not reach to touchpad gestures on touchpad. I tested it on macOS but I suspect it may malfunction also on other platforms.

when to update ?

hello! when is the update

ScrollableListView isn't focusable

If I tab through https://tvolkert.github.io/ I never get to the list boxes.

In general, tabbing through https://tvolkert.github.io/, I don't get to the check boxes, the link buttons, any of the widgets under "Lists", half of the widgets in the calendar section, up and down arrows down move between radio buttons, and nothing in the Tables section ends up getting focus.
