How can I achieve something like this?
That the textfields value is showing (...) when text is bigger than the remaining space
When the text input
I know we can use overflow: TextOverflow.ellipsis, in a Text widget. How can we do something similar in textfield value?
i think for now ,there is no parameter to set overflow on TextField
since the issue still open on official repository here.
maybe you can use another plugin like auto_size_text_field
AutoSizeTextField(
controller: _controller,
overflowReplacement: Text(
_controller.text,
style: const TextStyle(overflow: TextOverflow.ellipsis),
),

I am trying to use convex_bottom_bar lib, but when I try using a slightly longer title for a tab, it overflows. In the image below I tried to use the title Notifications, but it overflowed by 1 letter. I searched for solutions to this problem but I couldn't find any. Can someone help me?
Use auto_size_text package.
AutoSizeText(
'Notifications',
style: TextStyle(fontSize: 18),
minFontSize: 15,
maxLines: 1,
overflow: TextOverflow.ellipsis, // If you want to show ... after text like notifica...
)
Disclaimer:
I am very new to flutter, this is my first solo project that I am creating. All other projects have only been very short tutorials. The problem I am having (described below) may seem like a very easy fix, but as I am new please do explain it in detail as best you can, being able to visualize what you are saying also helps (through code, diagrams etc). Thank you.
Problem:
Unable to get auto_size_text maxLines to work correctly. On top of this, unable to get MaxFontSize working.
Further Explanation
I am using the auto_size_text package, setup with the pubspec.yaml dependency: auto_size_text: ^2.1.0 and import: 'package:auto_size_text/auto_size_text.dart'. I also changed my pubspec.yaml environment from sdk: ">=2.12.0 <3.0.0" to sdk: ">=2.11.0 <3.0.0" to allow non null safe packages to work - as per direction of this tutorial.
I am creating a container inside of my app, inside of this container is a Column widget, inside the Column widget are several rows. One of these rows is intended as a title. The code for it is below:
Row( // Row is inside of a Column which is inside of a Container
children: [
const SizedBox(width: 55), // Used to create padding either side of text
Expanded(
child: FittedBox(
child: AutoSizeText(
'70 | Brighton - Abbotsford and Green Island', // Header Example
maxLines: 2, // Cannot get this to work, always remains one line
maxFontSize: 20, // Does not work, always resizes to max font in order to fill whole FittedBox
style: TextStyle(
fontSize: 20, // Unsure if I need this, adding or removing seems to have to effect.
color: color.AppColor.textMain.withOpacity(0.8),
fontWeight: FontWeight.bold,
),
),
),
),
const SizedBox(width: 55), // Used to create padding either side of text
],
),
With this code I get this result - Note that the blue line is another row above the title but still inside of the same Column widget.
Desired Result:
The font is far too small, so I want it to be split among two lines. I am designing this container to be reused and I will later change it so the text is imported from a CSV file so name lengths will be varied. They all need to be readable, and while it's fine for smaller titles (example), larger ones need to have a bigger font while still fitting inside the same boundaries, so two lines is required. As also mentioned, I am unable to get the maxFontSize working, resulting in shorter titles having too large of a font.
Attempted Solutions:
I have tired using a null safe version of auto_size_text but was unable to get it working (as it's a prerelease I assume it isn't functioning properly).
I have another solution without using auto_size_text package
SizedBox(
child: TextField(
controller: _yourController,
decoration: InputDecoration(
border: InputBorder.none,
contentPadding: EdgeInsets.all(8),
),
textInputAction: TextInputAction.done,
keyboardType: TextInputType.multiline,
maxLines: null,
),
),
keyboardType: TextInputType.multiline makes TextField can be resized automatically and move to new line if it reach max width, and
maxLines: null makes your text can be written with many lines, and then
decoration here i use to remove TextField box border
Solved
I solved my own problem almost accidently while playing around with the code I posted in the original question.
Solution:
Although not the most convenient, the solution is to replace the Expanded widget and FittedBox to a SizedBox. Below is the adjusted code including comments about changes made.
Row( // Row is inside of a Column which is inside of a Container
children: [
const SizedBox(width: 55), // Used to create padding either side of text
SizedBox( // Changed the Expanded and FittedBox to a sized box with a width of 280, source container has a width of 390, so text is allowed a width of 280 once you subtract the width 55 SizedBox's either side
width: 280,
child: AutoSizeText(
'70 | Brighton - Abbotsford and Green Island', // Header Example
maxLines: 2, // Cannot get this to work, always remains one line
maxFontSize: 20, // Does not work, always resizes to max font in order to fill whole FittedBox
style: TextStyle(
fontSize: 20, // Unsure if I need this, adding or removing seems to have to effect.
color: color.AppColor.textMain.withOpacity(0.8),
fontWeight: FontWeight.bold,
),
),
),
const SizedBox(width: 55), // Used to create padding either side of text
],
),

I have a string and I would like to have an icon from the material icons displayed in that string. Currently, the only workaround is to use the standard emoji codes (e.g. '\u26A0').
I'm not quite sure how to do this. The reason I can't use a widget here is because I'm using a validator, and if the amount of characters are not met, the validator returns a string that reads out what the issue is. I'm trying to add a warning icon to it.
Would appreciate some help, thanks in advance!
The solution to your use case is WidgetSpan here is simple example of how to use it
Text.rich(
TextSpan(
children: <InlineSpan>[
TextSpan(text: 'call me'),
WidgetSpan(
child:Icon(Icons.phone)
),
],
)
),
I want to move the box that is full of red background over there to the position of the empty box.
In other words, I want to insert a container right next to the point where TextFormField ends.
Is this something that can be implemented in Flutter? Or is there no way?
-- UPDATE
I actually want to add a "send" Icon to the end of the text. All the examples I looked up were always going to the end of the Containers due to Rows, as shown in the photos I posted. Since the position of the send icon will always change, depending on the length of the text, in real time, this problem feels very difficult to me. and also for your information, this is not Text, but TextField or TextFormField widget.
Unfortunately, there is no way of doing this since TextFormField accepts string only and not a widget. Also, according to material guidelines, any such widget should be at the end of the text field as a suffix such as:
TextField(
controller: _controller,
decoration: InputDecoration(
hintText: "Enter a message",
suffixIcon: IconButton(
onPressed: () => _controller.clear(),
icon: Icon(Icons.clear),
),
),
)
May I ask what is the purpose?! maybe we can help find better solution then?
but if we have to then I can think of 2 ways.
1- Include the box as a Text - For example ▀ (Alt + 223)
var box = ▀
Text("efwewewefwewefe$box"),
2- Option 2: Wrap in a Stack widget
Stack(
children: [
Text("efwewewefwewefe"),
Container(height:5, width:5, color: Colors.red]),
I have a periodic function which appends text to a TextField.
For this purpose I set a TextEditingController and invoke: controller.text += someText.
However, when the TextField is scrolled and text is added, the TextField automatically scrolls back to the top and the just appended text gets out of view.
Is there any way to change the scroll behavior?
Set the selection using the TextEditingController.
This will prevent the TextField from rebuilding every time and/or moving the cursor to the start of the TextField.
TextField(
controller: textEditController,
onChanged: (content) {
textEditController..text = someText
..selection = TextSelection.collapsed(offset: textEditController.text.length);
},
)
I don't know if this can serve you already today but in case someone else sees the publication I hope that helps, I'll say that I do this with a SingleChildScrollView() and I set the reverse property to true. I have to say that I don't use a TexField(), you use a Text(), but it behaves well and every time the text increases a line automatically the reverse property of the SingleChildScrollView() causes it to scroll down and always see the last thing that is being written.
This is a small example of how I do it in my code:
Container(
alignment: Alignment.bottomRight,
height: size.height*0.044,
child: SingleChildScrollView(reverse: true,child: Text(valorOperacion1, style: GoogleFonts.exo(color: tema.hintColor, fontSize: 18.0.sp, fontWeight: FontWeight.w600,),))
),
