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 am facing an ui issue with TextFormField error border in focused state.
When I tapped inside TextFormField, width is getting double on focus as below screen shot
Could you please guide me what am i doing wrong here.
You are not doing anything wrong, this is a material design behavior, if you want to disable it , try this:
TextField(
decoration: InputDecoration(
label: Text('label'),
floatingLabelBehavior: FloatingLabelBehavior.never,// <--- add this
),
),
I implemented a page in my Flutter application that has a text input field and 2 time pickers that are activated by pressing the button to make them appear. The issue is that if I have a new value in the TextInputField and use one of the time pickers, after I'm done what I have typed in the input field will just reset.
Code snippet from the input field:
SizedBox(
width: 350,
child: TextField(
controller: titleController,
decoration: const InputDecoration(
border: OutlineInputBorder(),
hintText: 'Title',
),
onChanged: (value) {
title = value;
},
),
),
I've tried keeping the value of what is being typed in through a titleController and I have also attempted using the onChanged() method and a separate variable to keep the value in there. These solutions both didn't work for me, however. Is there any other solution to this issue?
If your TextField inside a stateless widget it will keep clearing the value of the controller everytime something pop on the screen, so try to put your TextField inside a stateful widget
I'm trying to implement this design:
i'm very beginner to flutter, and what i'm getting is this:
I don't want you guys to get me wrong, i'm not asking for someone to implement this for me.
i need guidance on how to:
remove the layout padding.
make a textview and edit text side by side look like one widget.
remove the space between the edit texts.
implement the CheckBox (i tried a row with check box and text, didn't work)
show a proper arrow in "Sign In" (instead of ->).
just some explanations, guidance and any documentation or tutorial that could be good for my case.
Here is my code
remove the layout padding.
make a textview and edit text side by side look like one widget.
Im not sure of this if your talking about inside TextFormField you can use contentPadding inside InputDecoration. But based on your layout design, you can separate the Label in TextFormField and create your own label text
Row(
children:[
Text("LABEL"),
Expanded(
child: TextFormField(),
)
]
)
4.implement the CheckBox (i tried a row with check box and text, didn't work)
Row(
children: [
Checkbox(
value: isValue,
onChanged: (bool value) {
setState(() {
isValue = value;
});
}),
Text("SOME TEXT"), //Read RichText widget for your design
],
),
For you arrow -> sign in
Try using Icon() widget
my problem:
The suggestionbox doesn't hide, except i choose one suggestion. hideSuggestionsOnKeyboardHide changes absolutely nothing...
I saw that others solved this problem with another package named keyboardvisibility.
But for me this is not a solution, beause i don't want the suggestionbox to disappear as soon as the keyboard disappears, I want the suggestionbox to disappear as soon as I tap somewhere outside the suggestionbox. Hope someone can help.
Here my code if it helps:
TypeAheadField(
hideOnEmpty: true,
hideOnError: true,
suggestionsBoxController: _suggestionsBoxController,
textFieldConfiguration: TextFieldConfiguration(
controller: typeAheadControllerA,
decoration: const InputDecoration(
hintText: 'Artikelnummer',
icon: const Icon(
Icons.business_center,
color: Colors.grey,
))),
suggestionsCallback: (pattern) {
return autoA
.where((autoA) =>
autoA.toLowerCase().contains(pattern.toLowerCase()))
.toList();
},
itemBuilder: (context, suggestion) {
return ListTile(
title: Text(suggestion),
);
},
transitionBuilder: (context, suggestionsBox, controller) {
return suggestionsBox;
},
onSuggestionSelected: (suggestion) {
typeAheadControllerA.text = suggestion;
},
)
Another minor problem/question:
How can i change the width of the suggestionbox / adapt to the width of the input field?
When I set the icon, logically the width of the input field decreased but the width of the suggestion box did not adapt to the width of the input field. I tried with suggestionsBoxDecoration offsetX. With offsetX I can move the box to the right, but the box keeps its width and therefore goes too far to the right but then i tried with wrapping the typeaheadfield in a padding widget or sizedbox but nothing works. If nobody knows how to solve this, I will probably remove the icons...
Thanks for help :)
You just use the keyboard "done" on iOS physical devices (I haven't tested it on Android yet - assuming there is something similar?), or click another field if there is one. The iOS simulator just doesn't bring up the keyboard when typing so it annoyingly seems like it can't be hidden without selecting a suggestion.
Tapping outside the field but not on another field doesn't unfocus normal TextFields either.
Use this metod: hideSuggestionsOnKeyboardHide: true,
You should wrap your scaffold with GestureDetector and with the property onTap() you call _suggestionBoxController.close();. Another thing if it does not work for you maybe you have a lot of code that is executed in one single file a simple refactoring can be your solution and set hideSuggestionsOnKeyboardHide : true (it was my case). For the width of the box suggestionBoxController.resize()
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,),))
),
