App will ANR when using google_mlkit_digital_ink_recognition running check model function

[empirejames]

Describe the bug
When I download the google_ml_kit_flutter-develop sample code and running the digital ink recognize function, It's take for a while for initialize the digitalInkRecognizeFunction... (And the app will cause ANR)

To Reproduce
Steps to reproduce the behavior:

1. Download sample code [google_ml_kit_flutter-develop].
2. Running it on debug or release mode
3. Click Vision APIs (dropdown list)
4. Click on Digital Ink Recognition function page's button "Check Model". (as attach picture)
5. It will show a progress dialog. (The app still alive then touch the device screen)
6. Wait for a moment and See error.
7. Remove app and reinstall again can reproduce.

Expected behavior
The app will not showing ANR.

Platform (please complete the following information):

• OS: Android 9
• Device: Samsung T820
• Flutter/Dart Version flutter SDK 3.19.3 / Dart 3.3.1
• Plugin version : 0.16.3 (the latest version)
