Describe the bug
This bug did not occur in flet 0.24.x versions, just in recent 0.25.x versions. Once I located this bug today, I tried removing try/except clause and there was information about error oddly enough. Still in it's current form it crashes all android apps with generic message.
Code sample
Code
```python
import flet as ft
async def main(page: ft.Page):
# crash android app start
try:
token = None
await page.client_storage.set_async("crystaltunes.token", token)
except Exception as e:
print(f"Exception occurred {e}")
# crash android app end
page.add(ft.Text("Hello, Flet!"))
ft.app(main)```
To reproduce
flet create someapp
cd someapp
(toss code into main.py)
flet build apk
Expected behavior
Exception should have shown at least something. What is strange is that code was working for long time up to 0.24.x.

Flet version
Name: flet Version: 0.25.0.dev3614
Regression
Yes, it used to work in a previous Flet version (please specify the version in additional details)
Suggestions
Need a more fine tuned approached to not let this error pass into dart code to crash the app as debugging this was a nightmare.
