Responsive Grid / Grid System #
Example: example_grid.dart
Grid system is very important when you create some web application. Especially for create responsive layout. This plugin is help to solve it
To create responsive layout you must using widget BsRow and BsCol or if in bootstrap use class="row" and class="col-*"




Create row container of grid system:
BsRow(
gutter: EdgeInsets.only(left: 10.0, right: 10.0, top: 5.0, bottom: 5.0),
children: <BsCol>[
// ...
]
);
copied to clipboard
After that you can add column:
BsRow(
//...
children: <BsCol>[
BsCol(
decoration: BoxDecoration(
border: Border.all(color: Colors.black),
),
padding: EdgeInsets.all(20.0),
sizes: ColScreen(sm: Col.col_12, lg: Col.col_6),
child: Center(child: Text('col-sm-12 col-lg-6')),
),
BsCol(
decoration: BoxDecoration(
border: Border.all(color: Colors.black),
),
visibility: BsVisibility.hiddenMd,
padding: EdgeInsets.all(20.0),
sizes: ColScreen(sm: Col.col_12, lg: Col.col_6),
child: Center(child: Text('col-sm-12 col-lg-6 col-hidden-md')),
),
BsCol(
decoration: BoxDecoration(border: Border.all(color: Colors.black)),
padding: EdgeInsets.all(20.0),
sizes: ColScreen(sm: Col.col_12, md: Col.col_12, lg: Col.col_6),
order: ColOrder(md: 1),
child: Center(child: Text('col-sm-12 col-md-12 col-md-6 col-order-lg-1')),
),
BsCol(
decoration: BoxDecoration(border: Border.all(color: Colors.black)),
padding: EdgeInsets.only(top: 10.0, bottom: 10.0),
sizes: ColScreen(md: Col.col_6),
child: BsRow(
children: [
BsCol(
decoration: BoxDecoration(
color: Colors.white,
border: Border.all(color: Colors.black),
),
padding: EdgeInsets.all(10.0),
sizes: ColScreen(md: Col.col_4),
child: Center(child: Text('Nested col-md-4')),
),
BsCol(
decoration: BoxDecoration(
color: Colors.white,
border: Border.all(color: Colors.black),
),
padding: EdgeInsets.all(10.0),
sizes: ColScreen(md: Col.col_4),
offset: ColScreen(lg: Col.col_4),
child: Center(child:Text('Nested col-md-4 col-offset-lg-4')),
),
],
),
),
]
// ...
)
copied to clipboard
Note #

Properties sizes in BsCol is has default value Col.col_12 or 100% of screen width
If need to ordering column use properties order with value BsScreen
If need to custom offset of column use properties offet with value BsScreen
BsVisibility.hiddenMd will hide widget in max screen medium or < 768 px, above it will show

// ...
copied to clipboard
Note #

To get selected value use getSelected or getSelectedAll
If you need returned string use getSelectedAsString, it will be returned string value with , separator
To set selected value use setSelected or setSelectedAll


To create a select box with server side data, use serverSide property
BsSelectBox(
hintText: 'Pilih salah satu',
searchable: true,
selectBoxController: _select3,
serverSide: selectApi,
)
copied to clipboard
Note #

To enable searchable option, set searchable property true
serverSide property need returned Future<BsSelectBoxResponse>

selectApi function
// ...
Future<BsSelectBoxResponse> selectApi(Map<String, String> params) async {
Uri url = Uri.http('localhost', 'api-json.php', params);
Response response = await http.get(url);
if(response.statusCode == 200) {
List json = convert.jsonDecode(response.body);
return BsSelectBoxResponse.createFromJson(json);
}

return BsSelectBoxResponse(options: []);
}
// ...
copied to clipboard
Json response data
[
{
"value":"1",
"text":"Tipe 01",
"typecd":"TP01"},
{
"value":"2",
"text":"Type 02",
"typecd":"TP02"
}
]
copied to clipboard
Note #

createFromJson is automatically put response data value, but you cant change it with define manual
If you want to make typecd as value of option, use value parameters of createFromJson

/// ...
if(response.statusCode == 200) {
List json = convert.jsonDecode(response.body);
return BsSelectBoxResponse.createFromJson(json,
value: (data) => data['typecd'],
);
}
/// ...
copied to clipboard

If you want to make typecd as text of option, use renderText parameters of createFromJson
renderText function need returned Widget

/// ...
if(response.statusCode == 200) {
List json = convert.jsonDecode(response.body);
return BsSelectBoxResponse.createFromJson(json,
value: (data) => data['typecd'],
renderText: (data) => Text(data['typecd'])
);
}
/// ...

ServerSide Datatables (with datatables response) #
Example: main.dart

To create a select box you need to import:
import 'package:bs_flutter_datatable/bs_flutter_datatable.dart';
copied to clipboard
Create source datatable:
class ExampleSource extends BsDatatableSource {

static List<BsDataColumn> get columns => <BsDataColumn>[
BsDataColumn(label: Text('No'), orderable: false, searchable: false, width: 100.0),
BsDataColumn(label: Text('Code'), columnName: 'typecd', width: 200.0),
BsDataColumn(label: Text('Name'), columnName: 'typenm'),
];

@override
BsDataRow getRow(int index) {
return BsDataRow(index: index, cells: <BsDataCell>[
BsDataCell(Text('${controller.start + index + 1}')),
BsDataCell(Text('${response.data[index]['typecd']}')),
BsDataCell(Text('${response.data[index]['typenm']}')),
]);
}
}
copied to clipboard
To create row event listener you musth defined listener on data source
class ExampleSource extends BsDatatableSource {

// ...

ValueChanged<dynamic> onEditListener = (value) {};
ValueChanged<dynamic> onDeleteListener = (value) {};

// ...

}
copied to clipboard
And then use variable on pressed action
// ...
@override
BsDataRow getRow(int index) {
return BsDataRow(index: index, cells: <BsDataCell>[
// ...
BsDataCell(Row(
children: [
TextButton(
onPressed: () => onEditListener(response.data[index]['typeid']),
child: Container(child: Text('Edit'))
),
TextButton(
onPressed: () => onDeleteListener(response.data[index]['typeid']),
child: Container(child: Text('Edit'))
)
],
))
// ...
]);
}
// ...
copied to clipboard
To handle that listener, you can set after request data success
Future loadApi(Map<String, dynamic> params) {
return http.post(
// ..
).then((value) {
// ...
setState(() {
// ...
_source.onEditListener = (typeid) {
/// Do edit
};
_source.onDeleteListener = (typeid) {
/// Do delete
};
});
});
}
copied to clipboard
declare source and controller datatable:
// ...
class _MyAppState extends State<MyApp> {

ExampleSource _source = ExampleSource();

@override
void initState() {
_source.controller = BsDatatableController();
super.initState();
}

// ...

}
copied to clipboard
create table view:
// ...
BsDatatable(
source: _source,
title: Text('Datatables Data'),
columns: ExampleSource.columns,
serverSide: loadApi,
)
// ...
copied to clipboard
Serverside function to get datatable response
// ...
Future loadApi(Map<String, dynamic> params) {
return http.post(
Uri.parse('http://localhost/flutter_crud/api/public/types/datatables'),
body: params,
).then((value) {
Map<String, dynamic> json = jsonDecode(value.body);
setState(() {
_source.response = BsDatatableResponse.createFromJson(json['data']);
_source.onEditListener = (typeid) {
/// Do edit
};
_source.onDeleteListener = (typeid) {
/// Do delete
};
});
});
}
// ...
copied to clipboard
Note #

After request data from server has been successfully you need to update response data souece

// ...
Future loadApi(Map<String, dynamic> params) {
return http.post(
// ...
).then((value) {
// ...
setState(() {
/// Update response source data
_source.response = BsDatatableResponse.createFromJson(json['data']);
// ...
});
});
}
// ..
copied to clipboard
To reload data you can use reload function
_source.controller.reload();
copied to clipboard
If you want to show data from List variable, you can add data to constructor source
class ExampleSource extends BsDatatableSource {

ExampleSource({
List? data,
}) : super(data: data);

// ....
}
copied to clipboard
And now you cant set List variable in your widget
class Datatables extends StatefulWidget {
@override
_DatatablesState createState() => _DatatablesState();
}

class _DatatablesState extends State<Datatables> {

ExampleSource _source1 = ExampleSource(
data: [
{'typecd': 'TP1', 'typenm': 'Type 1'},
{'typecd': 'TP2', 'typenm': 'Type 2'},
{'typecd': 'TP3', 'typenm': 'Type 3'},
{'typecd': 'TP4', 'typenm': 'Type 4'},
{'typecd': 'TP5', 'typenm': 'Type 5'},
]
);

// ....

}
copied to clipboard
If you want to add data dynamicaly from button or anything, you can call method add or addAll. And if you want to update you call method put for remove call method remove or removeAt
// ...
TextButton(
onPressed: () {
_source1.add({'typecd': 'TP1', 'typenm': 'Type ${_source1.datas.length}'});
},
child: Text('Add Row'),
)
// ...
