Flutter when text is bigger than input, text disappears - flutter

Question

The problem is that when the text is bigger than the input size, the text just disappears and I don't know why.
Here is my code:
TextField(
focusNode: _focusEmailNode,
controller: _emailController,
decoration: InputDecoration(
border: OutlineInputBorder(),
enabledBorder: OutlineInputBorder(
borderSide: BorderSide(color: txtEmailBoder),
),
hintText: 'Email',
),

Answer 1

After searching through many sites, I finally got a solution. You can solve this problem by giving decoration and maxlines in the textfield. Give isDense as true in InputDecoration
Example:
Container(
height: 20,
width: 100,
child: TextFormField(
maxLines: 1,
decoration: InputDecoration(
isDense: true,
contentPadding: EdgeInsets.fromLTRB(5.0, 1.0, 5.0, 1.0),
),
onChanged: (value) {
print(value);
},
),
);
if you don't give content padding then your text will be cut from the middle, like below.
Be careful when you give padding, you should give padding as needed by your textfield's height. If you give wrong padding then also your text will be invisible.

Answer 2

You need to add
contentPadding: EdgeInsets.zero
to your InputDecoration

Answer 3

Give text field an input formatter with desired length of the text like this:
inputFormatters: [
LengthLimitingTextInputFormatter(50),
],
And then have content padding set to like this :
contentPadding: EdgeInsets.fromLTRB(5.0 , 20.0 , 5.0 , 20.0),

Answer 4

Widget build(BuildContext context) {
return Scaffold(
body: Container(
padding: EdgeInsets.fromLTRB(5.0, 50, 5.0, 10.0),
alignment: Alignment.center,
child: TextField(
decoration: InputDecoration(
border: OutlineInputBorder(),
enabledBorder: OutlineInputBorder(
borderSide: BorderSide(color: Colors.blueAccent),
),
hintText: 'Email',
),
)));
}

Answer 5

To Prevent this disappearing use decoration as InputDecoration.collapsed(hintText: "Search Customer")
Full Code is TextField(decoration : InputDecoration.collapsed(hintText: "Search Customer"), textCapitalization: TextCapitalization.sentences)
