Overview

Hi! I use Gal.putImageBytes() and it saves image as image.png. Everything was fine, until the image(32).png, meaning that image(31).png is created perfectly fine, but next one is not. I've tested it by deleting image(31).png and it worked fine again, but not after it. I'm testing on POCO F4 with android 13.

I'm not sure if one will encounter the same error on other devices. But please, consider adding a String name = 'image.png' as a putImageBytes() paramater.

Steps to reproduce

Save any Uint8List image using Gal.putImageBytes
Repeat 31 times
Bug occures

Code sample

```dart Future _saveImage(Uint8List screenshot) async { try { await Gal.putImageBytes(screenshot); setState(() { _isSaving = false; }); } catch (e) { log(e.toString()); setState(() { _isSaving = false; }); } } ```

Thank you for filling this issue @Lo4D I have identified the cause of this.

https://takusan.negitoro.dev/posts/android_unique_file/

This article is in Japanese, but is well organized. And I am now working on a solution.

natsuk4ze commented 5 months ago

This issue has been resolved. The latest version will be uploaded to pub.dev later.

No changes have been made to add parameters to putImageBytes at this time. The problem is that Java only checks up to 31 times to create a unique file name. The best solution is to allow users to save media without worrying about duplicate names, not to allow users to specify names for avoiding duplicates.

Lo4D commented 5 months ago

Thanks for your fix, @natsuk4ze ! I wanted to specify a name not to allow users to specify a file name, but to save files with the name of my app, for example, and not generic image.png. I think it would not hurt to have such a paramater. But nonetheless, I'm glad you were able to fix this Java check-up thing

Thanks for your fix, @natsuk4ze !

You're welcome, adding a parameter to putImageBytes is not a bad idea, but it has nothing to do with this bug, so it was passed up.

Why there is a default value for the name parameter? if the user use it multiple times it will cause exception because image.png is already exists

Maybe it's better if it required instead of a default value?

natsuk4ze commented 5 months ago

it will cause exception because image.png is already exists

Is that true? The system should automatically avoid duplicates even if they have the same file name.

I updated gal_linux

static Future putImageBytes(Uint8List bytes, {String? album, required String name}) async { final fileName = '$name.png'; }

Is that code correct?

The implementation of gal_linux

I'm trying to update gal_linux to be compatible with 2.3.0 of gal

You have added a new parameter called name so I'm trying to adapt the new way of generating file name
