问题
I'm trying to format the appearance of FormBuilderRate within the flutter_form_builder package (link to package on pub.dev).
Specifically,
- How to eliminate or change the format of horizontal lines between items
- How to vertically align prefix Text (e.g., "Wwww..." in the screenshot below) with bottom or center of rating stars
- How to align right side of all four instances of prefix Text AND the left side of the rating stars, with a tighter gap between the prefix Text and left-most star (right now I'm using a hackey
padding: const EdgeInsets.onlyapproach)
Here's the code:
RichText(
text: TextSpan(
style: TextStyle(
color: Colors.blue,
),
children: <TextSpan>[
TextSpan(
text:
'[ 7 ] On a 1 - 5 star scale, with 5 being the best, how would you rate each of the following: ', // clipped " for this house"
style: TextStyle(
fontWeight: FontWeight.bold,
fontSize: 16.0,
),
),
TextSpan(
text:
' (optional)', // put 2 spaces instead of "\n (line break)
style: TextStyle(
fontWeight: FontWeight.normal,
fontStyle: FontStyle.italic,
fontSize: 14.0,
color: Colors.black54,
), // was 'misleading or inaccurate?',
),
],
),
),
SizedBox(
height: 6.0,
),
Padding(
padding: const EdgeInsets.only(left: 1.0),
child: FormBuilderRate(
attribute: 'zzz',
decoration: const InputDecoration(
// labelText: 'FormBuilderRate',
prefix: Text(
'Wwwwwwwwww',
style: TextStyle(
fontSize: 16,
),
),
),
initialValue: 0,
filledColor:
Color(0xffFFB900), // later: use starIconColor
emptyIcon: Icons.star_border_outlined,
emptyColor:
Color(0xffFFB900), // later: use starIconColor
isHalfAllowed: true,
halfFilledIcon: Icons.star_half,
halfFilledColor:
Color(0xffFFB900), // later: use starIconColor
iconSize: 32.0,
),
),
Padding(
padding: const EdgeInsets.only(left: 67.0),
child: FormBuilderRate(
attribute: 'zzz',
decoration: const InputDecoration(
//labelText: 'FormBuilderRate - kitchen:',
floatingLabelBehavior: FloatingLabelBehavior.auto,
prefix: Text(
'Xxxxxxx',
style: TextStyle(
fontSize: 16,
),
),
),
initialValue: 0,
filledColor:
Color(0xffFFB900), // later: use starIconColor
emptyIcon: Icons.star_border_outlined,
emptyColor:
Color(0xffFFB900), // later: use starIconColor
isHalfAllowed: true,
halfFilledIcon: Icons.star_half,
halfFilledColor:
Color(0xffFFB900), // later: use starIconColor
iconSize: 32.0,
),
),
Padding(
padding: const EdgeInsets.only(left: 30.0),
child: FormBuilderRate(
attribute: 'zzz',
decoration: const InputDecoration(
//labelText: 'FormBuilderRate - kitchen:',
floatingLabelBehavior: FloatingLabelBehavior.auto,
prefix: Text(
'Yyyyyyyyyyyy',
style: TextStyle(
fontSize: 16,
),
),
),
initialValue: 0,
filledColor:
Color(0xffFFB900), // later: use starIconColor
emptyIcon: Icons.star_border_outlined,
emptyColor:
Color(0xffFFB900), // later: use starIconColor
isHalfAllowed: true,
halfFilledIcon: Icons.star_half,
halfFilledColor:
Color(0xffFFB900), // later: use starIconColor
iconSize: 32.0,
),
),
Padding(
padding: const EdgeInsets.only(left: 56.0),
child: FormBuilderRate(
attribute: 'zzz',
decoration: const InputDecoration(
//labelText: 'FormBuilderRate - kitchen:',
floatingLabelBehavior: FloatingLabelBehavior.auto,
prefix: Text(
'Zzzzzzzz',
style: TextStyle(
fontSize: 16,
),
),
),
initialValue: 0,
filledColor:
Color(0xffFFB900), // later: use starIconColor
emptyIcon: Icons.star_border_outlined,
emptyColor:
Color(0xffFFB900), // later: use starIconColor
isHalfAllowed: true,
halfFilledIcon: Icons.star_half,
halfFilledColor:
Color(0xffFFB900), // later: use starIconColor
iconSize: 32.0,
),
),
UPDATE #1 with partial answer:
@Miller's answer below using InputDecoration(border: InputBorder.none), removes the lines, but does not fix the problem of aligning prefix Text and stars.
Even so, here's the partial solution code:
Row(
mainAxisAlignment: MainAxisAlignment.end,
children: [
Flexible(
flex: 1,
child: FormBuilderRate(
attribute: 'www',
decoration: const InputDecoration(
border: InputBorder.none,
prefix: Text(
'Row+Flexible Wwww',
style: TextStyle(
fontSize: 16,
),
textAlign: TextAlign.end,
),
),
initialValue: 0,
filledColor:
Color(0xffFFB900), // later: use starIconColor
emptyIcon: Icons.star_border_outlined,
emptyColor:
Color(0xffFFB900), // later: use starIconColor
isHalfAllowed: true,
halfFilledIcon: Icons.star_half,
halfFilledColor:
Color(0xffFFB900), // later: use starIconColor
iconSize: 32.0,
),
),
],
),
Row(
mainAxisAlignment: MainAxisAlignment.end,
children: [
Flexible(
flex: 1,
child: FormBuilderRate(
attribute: 'Xxxx',
decoration: const InputDecoration(
border: InputBorder.none,
prefix: Text(
'Row+Flexible',
style: TextStyle(
fontSize: 16,
),
textAlign: TextAlign.end,
),
),
initialValue: 0,
filledColor:
Color(0xffFFB900), // later: use starIconColor
emptyIcon: Icons.star_border_outlined,
emptyColor:
Color(0xffFFB900), // later: use starIconColor
isHalfAllowed: true,
halfFilledIcon: Icons.star_half,
halfFilledColor:
Color(0xffFFB900), // later: use starIconColor
iconSize: 32.0,
),
),
],
),
Padding(
padding: const EdgeInsets.only(left: 30.0),
child: FormBuilderRate(
attribute: 'yyy',
decoration: const InputDecoration(
border: InputBorder.none,
prefix: Text(
'Yyyyyyyyyyyy',
style: TextStyle(
fontSize: 16,
),
),
),
initialValue: 0,
filledColor:
Color(0xffFFB900), // later: use starIconColor
emptyIcon: Icons.star_border_outlined,
emptyColor:
Color(0xffFFB900), // later: use starIconColor
isHalfAllowed: true,
halfFilledIcon: Icons.star_half,
halfFilledColor:
Color(0xffFFB900), // later: use starIconColor
iconSize: 32.0,
),
),
Padding(
padding: const EdgeInsets.only(left: 56.0),
child: FormBuilderRate(
attribute: 'zzz',
decoration: const InputDecoration(
border: InputBorder.none,
prefix: Text(
'ZzzzzzzZ',
style: TextStyle(
fontSize: 16,
),
),
),
initialValue: 0,
filledColor:
Color(0xffFFB900), // later: use starIconColor
emptyIcon: Icons.star_border_outlined,
emptyColor:
Color(0xffFFB900), // later: use starIconColor
isHalfAllowed: true,
halfFilledIcon: Icons.star_half,
halfFilledColor:
Color(0xffFFB900), // later: use starIconColor
iconSize: 32.0,
),
),
And here's what this looks like in the Android emulator (first two rating rows use @Miller's approach, which does not fix the #2 prefix vertical text alignment problem):
UPDATE #2: solved issue of vertically aligning prefix Text with rating stars:
Based on part of @Joe Muller's answer here, I made the actual text transparent, added a shadow, then positioned the shadow higher than the original text.
Here's that part of the code:
style: TextStyle(
fontSize: 16,
**color: Colors.transparent,
shadows: [
Shadow(
color: Colors.black54,
offset: Offset(0, -7))
],**
),
And here's a screenshot with the changes:
What's left is #3 from my original question: How to align right side of all four instances of prefix Text AND the left side of the rating stars, with a tighter gap between the prefix Text and left-most star (right now I'm using a hackey padding: const EdgeInsets.only approach)
回答1:
To make changes to a field's underline, you could make use of the
borderattribute ofInputDecoration. For example, to remove the whole underline:border: InputBorder.none,& 3. Kindly note that FormFields, like many other widgets, tend to take all the available width of their parent widget. I would therefore advise using a row between the Text and FormBuilderRate so as to have better control of the positioning of your widgets; like so:
Row(
mainAxisAlignment: MainAxisAlignment.end,
children: [
Flexible(
flex: 1,
child: Text(
'Wwwwwwwwww',
style: TextStyle(fontSize: 16),
textAlign: TextAlign.end,
),
),
Flexible(
flex: 1,
child: FormBuilderRate(
attribute: 'zzz',
decoration: const InputDecoration(
border: InputBorder.none
),
initialValue: 0,
filledColor: Color(0xffFFB900),
emptyIcon: Icons.star_border_outlined,
emptyColor: Color(0xffFFB900),
isHalfAllowed: true,
halfFilledIcon: Icons.star_half,
halfFilledColor: Color(0xffFFB900),
iconSize: 32.0,
),
),
],
),
