Crash when opening large file (OutOfMemoryError) on Android

[tienna-0051]

Environment:

• Drift version: 0.3.6
• Platform: Android
• Device: Pixel 4
• OS: Android 13

Description:
The app crashes when attempting to open a large file. The crash appears to be caused by excessive memory allocation during file processing, leading to an OutOfMemoryError.

Steps to Reproduce:

1. Launch the app
2. Attempt to open a large file (size not precisely measured, but large enough to trigger memory issue)
3. Observe crash

Expected Behavior:
The app should handle large files gracefully (e.g., streaming, chunking, or rejecting with a clear error), without crashing.

Actual Behavior:
The app crashes with OutOfMemoryError.

Yes I have noticed this as well. Wil try to figure out why it happens

#45 I asked AI (Claude Sonnet 4.6 High) to help analyze and fix this issue, and created a PR (it's me, just another account)
The PR content was generated by AI.
I’ve tested it on Android and it seems to work in my cases. You might want to take a look and evaluate it.
I’m not a professional Flutter/Rust developer, so please treat this as a reference rather than a definitive fix.
Hopefully it’s still useful.
