So I have this unique requirement as shown in the picture below, where the blue texts are user inputs. I have been doing my own research regarding this and have found a few viable solutions, out of which a custom TextEditingController
seems most promising. I haven't started implementation but out of the top of my head, I think I might run into some problems with the touch and cursor controls later on.
Now my question is, Is there a better way that I might have overlooked? Is there a way to gracefully handle which areas are touchable, handle the cursor when deleting, and moving to the next focus?

As suggested by @Andrey Gordeev, we can use a Wrap Widget
with a children
defined as follows:
Wrap(
alignment: WrapAlignment.center,
runAlignment: WrapAlignment.center,
children: [
const Text('Hala, we\'re '),
SizedBox(
width: 50,
height: 20,
child: TextField(
controller: TextEditingController.fromValue(
const TextEditingValue(text: 'aryab'),
),
),
),
const Text(' You? I\'m '),
SizedBox(
width: 150,
height: 20,
child: TextField(
controller: TextEditingController.fromValue(
const TextEditingValue(text: 'Someone Awesome'),
),
),
),
],
)
This renders the result of the screenshot attached:
A full example snippet can be found below:
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return const MaterialApp(
title: 'Demo',
home: MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key}) : super(key: key);
@override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child:
Wrap(
alignment: WrapAlignment.center,
runAlignment: WrapAlignment.center,
children: [
const Text('Hala, we\'re '),
SizedBox(
width: 50,
height: 20,
child: TextField(
controller: TextEditingController.fromValue(
const TextEditingValue(text: 'aryab'),
),
),
),
const Text(' You? I\'m '),
SizedBox(
width: 150,
height: 20,
child: TextField(
controller: TextEditingController.fromValue(
const TextEditingValue(text: 'Someone Awesome'),
),
),
),
],
),
),
);
}
}

While there are two types of widgets, <plainText,inputText>
can be placed here, and we need to concern about retrieving full text from the form/text.
Creating a map for the widgets will be a good choice, I think.
final Map<String, String?> _textsInForm = {
"Hala, we're": null,
"aryab": "groupName",
". You? I'm": null,
"Someone Awysome": "myself",
",a": null,
"Driver": "job",
};
As you can see, I'm using key
as main value and value
as nullable string. If we find null-string, it will be simply Text
widget, else TextFiled
.
I'm using RichText
to handle this situation.
We will create list List<InlineSpan>
for RichText
and List<TextEditingController>
to handle input text.
I'm using StatelessWidget
, while having stateFullWidget
handle creation on initState
.
There is one issue, it is taking minimum hint text width. You can try with passing text on TextEditingController
instead.
import 'package:flutter/material.dart';
class SomeTextEditable extends StatelessWidget {
SomeTextEditable({Key? key}) : super(key: key);
final Map<String, String?> _textsInForm = {
"Hala, we're": null,
"aryab": "groupName",
". You? I'm": null,
"Someone Awysome": "myself",
",a": null,
"Driver": "job",
};
final TextStyle _hintTextStyle = const TextStyle(
color: Colors.grey,
);
final TextStyle _textFiledStyle = const TextStyle(
color: Colors.blue,
);
WidgetSpan _textFiled(TextEditingController controller, String hint) =>
WidgetSpan(
alignment: PlaceholderAlignment.middle, // set middle according to texts
child: IntrinsicWidth(
//flexiable size
child: TextField(
style: _textFiledStyle,
controller: controller,
decoration: InputDecoration(
hintStyle: _hintTextStyle,
hintText: hint,
border: InputBorder.none,
),
),
),
);
@override
Widget build(BuildContext context) {
List<TextEditingController> controllers = [];
List<InlineSpan> textSpans = [];
_textsInForm.forEach((key, value) {
if (value != null) {
TextEditingController controller = TextEditingController();
controllers.add(controller);
textSpans.add(_textFiled(controller, key));
} else {
textSpans.add(TextSpan(text: "$key "));
}
});
return Scaffold(
body: Column(
children: [
RichText(
text: TextSpan(children: textSpans),
),
ElevatedButton(
onPressed: () {
String result = "";
int i = 0;
_textsInForm.forEach((key, value) {
if (value != null) {
final textFromIcontroller = controllers[i ].text;
result = "$textFromIcontroller ";
} else {
result = "$key ";
}
});
print(result);
},
child: Text("Get Text"),
),
],
),
);
}
}
