It may sound easy but How can we do a multi-line editable textfield in flutter? TextField works only with a single line.
Edit: some precisions because seems like it's not clear.
While you can set multiline to virtually wrap the text content, it's still not multiline. It's a single line displayed into multiple lines.
If you want to do something like this then you can't. Because you don't have access to ENTER button. And no enter button means no multiline.
Set maxLines to null and it will auto grow vertically.
It's documented (but not entirely clearly) here (edit: I've created a PR to update this, which I should've done to begin with for this question ;). To figure it out I ended up looking at the code for TextField and its superclass(es), seeing what the behavior would be if set to null.
So your code should be as follows:
new TextField(
decoration: const InputDecoration(
hintText: 'Reply',
labelText: 'Reply:',
),
autofocus: false,
focusNode: _focusnode,
maxLines: null,
controller: _newreplycontroller,
keyboardType: TextInputType.text,
),
If you're trying to make it autogrow horizontally, you probably shouldn't - at least not based on the text content. But I'm asuming you want to make it autogrow vertically.
1. Solution Summary
FlatButton and RaisedButton are deprecated.
So, you can use shape which placed in the style property, for TextButton and ElevatedButton.
There are some changes since Flutter 2.0:
style: the property type has changed to ButtonStyleshape: the property type has changed to MaterialStateProperty<T>2. Rounded Button
Inside the style property exists the shape property:
style: ButtonStyle(
shape: MaterialStateProperty.all<RoundedRectangleBorder>(
RoundedRectangleBorder(
borderRadius: BorderRadius.circular(18.0),
side: BorderSide(color: Colors.red)
)
)
)
Square Button
For a square button you can use ElevatedButton or otherwise add:
style: ButtonStyle(
shape: MaterialStateProperty.all<RoundedRectangleBorder>(
RoundedRectangleBorder(
borderRadius: BorderRadius.zero,
side: BorderSide(color: Colors.red)
)
)
)
Complete Example
Row(
mainAxisAlignment: MainAxisAlignment.end,
children: [
TextButton(
child: Text(
"Add to cart".toUpperCase(),
style: TextStyle(fontSize: 14)
),
style: ButtonStyle(
padding: MaterialStateProperty.all<EdgeInsets>(EdgeInsets.all(15)),
foregroundColor: MaterialStateProperty.all<Color>(Colors.red),
shape: MaterialStateProperty.all<RoundedRectangleBorder>(
RoundedRectangleBorder(
borderRadius: BorderRadius.circular(18.0),
side: BorderSide(color: Colors.red)
)
)
),
onPressed: () => null
),
SizedBox(width: 10),
ElevatedButton(
child: Text(
"Buy now".toUpperCase(),
style: TextStyle(fontSize: 14)
),
style: ButtonStyle(
foregroundColor: MaterialStateProperty.all<Color>(Colors.white),
backgroundColor: MaterialStateProperty.all<Color>(Colors.red),
shape: MaterialStateProperty.all<RoundedRectangleBorder>(
RoundedRectangleBorder(
borderRadius: BorderRadius.zero,
side: BorderSide(color: Colors.red)
)
)
),
onPressed: () => null
)
]
)

To use auto wrap, just set
maxLinesasnull:If the
maxLinesproperty isnull, there is no limit to the number of lines, and the wrap is enabled.
