Writing/ Pasting long lenghty text into TextField.

[faro vitus]

I am creating a note app using Flutter, and as we know we may need to write or paste a short/medium/long lengthy text and save them right ? Well TextField only works for me on short/medium lengthy notes while for long ones it just doesn't save it.

1- I should let you know that i am perfectly able to save/edit short/medium notes so the issue can't be related to database or controller.
2- In case of pasting a long text in textfield the textField Expands and show the whole note but when you hit the save button and automatically get to homescreen i see a blank note.
3- I am using sqflite for database in case you all need to know, and added a part of the code related to textfield below.
4- Btw i am able to paste the same long text in Google Keep so i don't see why i have such limitation in my Flutter app.
5- Tried setting maxLines to null and that didn't help as well.
6- I am using Flutter 1.22.0 Stable

import 'package:flutter/material.dart'; class NoteContentState extends State<NoteContent> { DatabaseHandler handler = DatabaseHandler(); TextEditingController noteController = TextEditingController(); @override Widget build(BuildContext context) { return Scaffold( body: Padding( padding: EdgeInsets.only(top: 15.0, bottom: 15.0), child: TextField( controller: noteController, onChanged: (text) { update(); }, decoration: InputDecoration( labelText: 'Note', border: OutlineInputBorder( borderRadius: BorderRadius.circular(5.0) ) ), ), ), ); } }

Can you create and share a Youtube of the behavior?

Can you share minimum reproducible code as a Github project?

How big is lengthy note? 100 characters?

Any error message do you observe? A blank appears when there’s an error and the app is built with release mode. Do you see the same blank when you run the debug mode?

Hi thanks for your quick reply and for your understanding. 

I talked about the issue in here but unfortunately i was not able to be clear enough to let them understand the issue.

https://github.com/flutter/flutter/issues/67841

I can create a video later today showing the abnormal behavior, also the text might be +1000 characters cause as i said in my case (creating a note app) sometimes user might need to write or copy an article and save it and that’s where the issue happens. If a user decide to write a short or medium notes than everything works as expected.

Yes, making others understand your problem is not an easy task.

Looking forward to the video and the minimum reproducible project.

https://youtu.be/p2iJwe_uRZ4 Test 2 ( see how it have same behavior if i pressed the back key)

Also i used this website to generate a long text to paste in textField

Nice. I see that pasted text somehow disappears when you hide the keyboard. This could be a bug in your app or Flutter. Can you create a minimum reproducible project in GitHub?

In the course of creating the project, you'll identify whether it's related to SQLite or not.

I shared this link on GitHub maybe you can try it out and help with this please ?

This code ^ does not use a database.

Personally on my project I don’t think that database is the problem because it works fine when you try anything else, the textField or controller just can’t handle that many characters i guess and ends up not passing the new data to database.

[Suzuki Tomohiro]

(I don’t run the project) By any chance, this piece of code resets the text?
