This change reverts the following previous change:
Resolves partly #165510


**Context:** This issue originates from
#99715, where it was reported
that `liveRegion` alone was insufficient for announcing form validation
errors. While `liveRegion` announces the first error encountered,
subsequent submissions with the same error message on Android would not
trigger a re-announcement.

**Original Solution:** Pull request
#123373 addressed this by
implementing the `announce` event to ensure error messages were
consistently announced, even for repeated submissions.

**Native Android Behavior (Jetpack Compose):** In native Android
development using Jetpack Compose, setting the `isError` property of a
`TextField` to `true` triggers Talkback to announce "Error invalid
input." This announcement occurs *only* on the initial change to the
error state. Subsequent errors, even if the `isError` property remains
`true`, are not re-announced. This behavior closely mirrors the
functionality of `liveRegion`, with the key difference being that
`liveRegion` also announces the specific error text, in addition to the
general error state. Testing in a native Jetpack Compose application
confirms this behavior and provides a valuable comparison point against
the current Flutter form example.

**Suggested Action:** **Fork** the behavior in
#123373. Reinstate the use of
`liveRegion` for error announcements within `widgets/Form` for Android
and keep other platforms the same.

…165531" (#168992)

Partly of #165510

⤴️ Parent PR: #169685 (✅ Merged)
⤴️ Parent PR (refactor): #170618
(✅ Merged)

Re-lands #165531
The PR was originally reverted due to an issue with an internal Google
test. I added a new test case under `input_decorator_test.dart` which
does something similar to prevent the regression. All other code is the
same as #165531.

The easiest way to review this would probably be to just check the [diff
after the first
commit](cb5647c)
to see the changes I made. To check if the reland commit is the same, it
might be best to just [compare solely that
commit](9bd8d56)
against the [original
PR](https://github.com/flutter/flutter/pull/165531/files).

…lutter#165531" (flutter#168992)

Partly of flutter#165510

⤴️ Parent PR: flutter#169685 (✅ Merged)
⤴️ Parent PR (refactor): flutter#170618
(✅ Merged)

Re-lands flutter#165531
The PR was originally reverted due to an issue with an internal Google
test. I added a new test case under `input_decorator_test.dart` which
does something similar to prevent the regression. All other code is the
same as flutter#165531.

The easiest way to review this would probably be to just check the [diff
after the first
commit](flutter@cb5647c)
to see the changes I made. To check if the reland commit is the same, it
might be best to just [compare solely that
commit](flutter@9bd8d56)
against the [original
PR](https://github.com/flutter/flutter/pull/165531/files).
