Is there a way to scan datamatrix QR codes in Dart ?
Does anyone know a lib that could answer my needs ?
I found this lib : barcode_scanner but it's part of the Scanbot SDK Scanner that isn't free to use.
I'm looking for something more opensource and in the best case scenario, free to use without a license.
Thanks in advance
Try flutter_barcode_scanner package it can solve your problem and it also has good documentation to get started with. It is also free and Open Source.

I am a beginner in flutter and would like your help.
I want to get the Google Services Frameword Identifier (gsfid) in a flutter app, but i can't find any plugin for that. I found a fairly old post on how to do it using java, but I couldn't get it to work, as flutter, if I understood correctly, uses kotlin and unfortunately I'm neither a java nor kotlin expert.
I read all the stuff about deviceID and Android_id, which is confusing enough on its own without starting to mention other "unique" ids (e.g. ad id etc).
I have concluded that what suits me for use in the particular application I have designed is the gsf id.
So if anyone knows the subject and is kind enough to help me, I will be grateful and thank you in advance.

I tried to convert the java code I found se kotlin and connect it (methodChannel) to my flutter application, but without any luck
Hi it's my first time using esp32-S2 because now its not recommended to use esp32. I'm looking for saving images in SPIFFS for my web server. In esp32 i used to use esp32fs plugin (https://github.com/me-no-dev/arduino-esp32fs-plugin) but it doesn't work for esp32-S2. I would like to know if there is any plugin like esp32fs and if not how can i save my images (I'm using arduinoIDE 1.8.19). I've been searching but i didn't found anything. Any orientation is welcomed. Thank you for your time and assistance.
You can try my ESP32_FSWebServer_DRD or ESP_FSWebServer example of ESP_WiFiManager library
Follow the instructions in ESP_FSWebServer Example
You can use either deprecated SPIFFS or the better LittleFS
Which the best library in Flutter to read UDIGI 2.0 medical device codes ?
All libraries I use, like: 'package:flutter_barcode_scanner/flutter_barcode_scanner.dart';
answers PYTHON-BARCODE+.
Thank you in advance
Problem solved since not existent, the barcode tried to read was wrong, even if published as an example. Strange the code read: PYTHON-BARCODE+ Any other code UDI is readable by any library I tried.

thanks in advance
Do you only want to use haru library?? If it is not really needed.. then below link is really good for generating any type of PDFs. Also manipulating functions inside this link is really easy.. And integrations is also too easy without any additional framework and also fast.... Please follow the link

I'm trying to create a RichTextArea (following the GWT Showcase : link )
When I do a code completion of RichTextToolbar, I'm not able to find it. Is this an external library?
And then I googled and found this : google code link. Is this the same library in the Google Showcase? Or is the RichTextToolbar is an old implementation that not being brought to version 2.3?
Update:I tested this and what I feel is although the implementation the same, the UI looks different though.
It seems that they created their own version of RichTextToolbar.
This class is part of the GWT Showcase.
Here is a decent explanation to get the RichTextToolbar working. You take the source code from showcase basicaly.
