A flutter package to help apps with extensive forms, implementing inputs as BottomSheet to make it enjoyable.

flutter-input-sheet #

Pub License: MIT

A pack of input types implemented as a sheet! 🚀

Overview #

flutter-input-sheet is a package that shows inputs on sheets.

It was created with the purpose of make simple and pleasant extensive forms. You can create custom components to present your data and edit them in sheets for each one.

It was developed by abstracting and implementing great packages in pub.dev to create a single and simple pack for forms.

Installation #

add this line to pubspec.yaml

input_sheet: <latest_version>

Dependencies #

Also, this package uses some other libraries that need to be imported in your project to work, this libraries is used in some input types that need constants informed at params.

camera: ^0.5.8+1
video_compress: ^2.0.0
flutter_cupertino_date_picker: ^1.0.12

IOS #

You will need to add permissions in your Info.plist to use camera and microphone once the package has an input for photos and videos

<key>NSCameraUsageDescription</key>
<string>Can I use the camera please?</string>
<key>NSMicrophoneUsageDescription</key>
<string>Can I use the mic please?</string>

Android #

You will need to add permissions in your AndroidManifest.xml to read and write external storage and manage the camera once the package has an input for photos and videos

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="18" />

⭐ Basic components #

Was created some basic components to show data information on screen before open the input sheet.

  • IpsCard

  • IpsLabel

  • IpsError

  • IpsIcon

  • IpsValue

  • IpsPhoto

  • IpsVideo

Examples #

Basic card component: #

This library implements a basic and optional card component to simplify its forms when presenting data.

//Your component to show data
IpsCard(
    label: IpsLabel("Name"),
    value: IpsValue(_name ?? "Touch to edit..."),
    icon: IpsIcon(FeatherIcons.user),
    error: IpsError(_errors['name']),
    onClick: () {
        //Your sheet implementation
    },
);

Basic media component: #

Also for media types, you may want to preview the media, so I created a simple component to show Photo and Video.

//Photo component preview file
IpsPhoto(
    file: _photo,
    onClick: (){
        //Your sheet implementation
    }
);

//Video component preview thumbnail
IpsVideo(
    thumbnail: _thumbnailVideo,
    onClick: (){
        //Your sheet implementation
    },
);

Opening a sheet: #

InputSheet(
    //InputSheet implements the scope information of sheet
    context,
    label: "Name",
    cancelText: "Cancel",
    doneText: "Confirm",
).text(
    //.text or any other option available type implemets the input type
    placeholder: "Type here...",
    value: _name,
    onDone: (dynamic value) => setState(() {
        _name = value;
    }),
);

Complete simple example: #

class _MyHomePageState extends State<MyHomePage> {
  String _name;
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: SingleChildScrollView(
        child: Padding(
          padding: EdgeInsets.all(25),
          child: IpsCard(
                label: IpsLabel("Name"),
                value: IpsValue(_name ?? "Touch to edit..."),
                icon: IpsIcon(FeatherIcons.user),
                error: IpsError(_errors['name']),
                onClick: () => InputSheet(
                  context,
                  label: "Name",
                  cancelText: "Cancel",
                  doneText: "Confirm",
                ).text(
                  placeholder: "Type here...",
                  value: _name,
                  onDone: (dynamic value) => setState(() {
                    _name = value;
                  }),
                ),
            ),
        ),
      ),
