Answer 1

Not 100% sure how you imagine your layout.
You plan to add more search tags? Change the flex values if you want to.
If you want to have your rows right under the FilterListWidget, than add mainAxisAlignment: MainAxisAlignment.start to second Column.
SafeArea(
child: Column(
children: [
Flexible(
flex: 2,
child: FilterListWidget(
allTextList: countList,
hideheaderText: true,
selectedTextBackgroundColor: Colors.red,
applyButonTextBackgroundColor: Colors.red,
allResetButonColor: Colors.grey,
onApplyButtonClick: (list) {
//Navigator.pop(context, list);
},
),
),
Flexible(
flex: 3,
child: Column(
mainAxisAlignment: MainAxisAlignment.end,
children: [
Row(
children: [
Container(
width: 180,
child: TexstInput(lable: 'min-Upvote',icons: Icons.favorite,),
),
Container(
width: 180,
child: TexstInput(lable: 'max-Upvote'),
),
],
),
Row(
children: [
Container(
width: 180,
child: TexstInput(lable: 'min',icons: Icons.person,),
),
Container(
width: 180,
child: TexstInput(lable: 'max'),
),
],
),
Container(
child: RaisedButton(child:Text(
'apply'
),),
),
],
),
),
],
),
)

Try with the below lines
Expanded(
child: Row(
children: [
Container(width: 2 ),
Expanded(
child: TexstInput(lable: 'min-Upvote',icons: Icons.favorite,),
),
Container(width: 2 ),
Expanded(
child: TexstInput(lable: 'max-Upvote'),
),
Container(width: 2 ),
],
),
),
Expanded(
child: Row(
children: [
Container(width: 2 ),
Expanded(
child: TexstInput(lable: 'min',icons: Icons.person_rounded,),
),
Container(width: 2 ),
Expanded(
child: TexstInput(lable: 'max'),
),
Container(width: 2 ),
],
),
),
