What's new in Flutter 3.10

Insert content text input client

Added an `insertContent` method to the `TextInputClient` interface to allow Android's image keyboard feature to insert content into a Flutter `TextField`.

Resolve the Android Java Gradle error

If you've recently upgraded Android Studio to the Flamingo release and have either run or built an existing Android app, you might have run into an error similar to the following:

Require one data variant for ClipboardData constructor

The `ClipboardData constructor`'s `text` argument is no longer nullable. Code that provides `null` to the `text` argument must be migrated to provide an empty string `''`.

"Zone mismatch" message

Starting with Flutter 3.10, the framework detects mismatches when using Zones and reports them to the console in debug builds.

Deprecated API removed after v3.7

In accordance with Flutter's Deprecation Policy, deprecated APIs that reached end of life after the 3.7 stable release have been removed.

Deprecated the window singleton

In preparation for supporting multiple views and multiple windows, the `window` singleton has been deprecated. Code previously relying on the `window` singleton needs to look up the specific view it wants to operate on via the `View.of` API or interact with the `PlatformDispatcher` directly.
