commit c60f33e229e31ab328ef6b59dab63b264954831c
Author: Alexandre Elias <aelias@google.com>
Date: Fri Jul 10 16:23:09 2020

Semantics no-op cleanups

Partly in response to lmr's broad code review, I did a pass of
superficial API/implementation cleanup. The main changes are:

- I changed each Boolean SemanticsProperty where false is equivalent to
not being present to take "Unit" instead. This is conceptually
clearer: it avoids questions like "can I cancel out a semantics from a
merged child by setting it to false?" Because "property = Unit" looks
weird, I also changed the style of these to "property()".

- I moved the Semantics id generator closer to where it's used, in
SemanticsModifierCore. I made it internal and an AtomicInt.
(Note that integer ids are heavily used in the Android
AccessibilityNodeInfo APIs so I can't simply remove them entirely.)

- I deleted dead code. Some examples include SemanticsHintOverrides,
a public API not connected to anything, and SemanticsPropertyKey
merge() open method which is never called. (In both cases I have
a different plan in mind for accessibility.)

Fixes: 145951226
Fixes: 145955412
Test: existing tests
Relnote: "Single-value semantics properties now use a calling style.
For example, 'semantics { hidden = true }' is now written as:
'semantics { hidden() }'."

Reassigned to an...@google.com.

Fundamentally the issue here is that the selection logic happening in composition depends on the text layout result which is available on measure. So we end up using stale TextLayoutResult which causes the issue.

This is the same exception as in b/229378536 and b/221580975 as well, and it also involves selection, so I'm wondering if those two bugs have the same cause Anastasia described.

ha...@google.com <ha...@google.com> #5Jun 23, 2022 12:49PM

There is a similar problem regarding Magnifier but I don't think these are directly related. The main cause for this issue is the async relation between TextFieldValue and layoutResult. Magnifier related crashes don't seem to be caused by changes in TextFieldValue or layout.

commit c1e913cdea06ac6cf01c596000d375013f1a1d7c
Author: Halil Ozercan <halilibo@google.com>

Fix crash when selected text is cleared by state changes and re-added later

BasicTextField's String API manages the selection and composition completely internally. Therefore, its selection value stays the same across value changes that comes from hoisted state, instead of IME commands. In a case where selected text is removed by a state change and later added, text layout result lags behind. This change makes sure that selection handles are only drawn when layout result is in sync with the latest TextFieldValue.

Test: CoreTextFieldSelectionContentChangeTest.kt
Relnote: Fixed a crash where TextField is cleared and refilled while selection is active.
