How to Move bottomsheet along with keyboard which has textfield(autofocused is true)?

Question

Add isScrollControlled = true to BottomSheetDialog it'll allow the bottom sheet to take the full required height which gives more insurance that TextField is not covered by the keyboard.

Add Keyboard padding using MediaQuery.of(context).viewInsets.bottom

Note

If your BottomSheetModel is Column make sure you add mainAxisSize: MainAxisSize.min, otherwise the sheet will cover the whole screen.

Example

 showModalBottomSheet(
    shape: RoundedRectangleBorder(
        borderRadius: BorderRadius.vertical(top: Radius.circular(25.0))),
    backgroundColor: Colors.black,
    context: context,
    isScrollControlled: true,
    builder: (context) => Padding(
      padding: const EdgeInsets.symmetric(horizontal:18 ),
      child: Column(
            crossAxisAlignment: CrossAxisAlignment.start,
            mainAxisSize: MainAxisSize.min,
            children: <Widget>[
              Padding(
                padding: const EdgeInsets.symmetric(horizontal: 12.0),
                child: Text('Enter your address',
                    style: TextStyles.textBody2),
              ),
              SizedBox(
                height: 8.0,
              ),
              Padding(
                padding: EdgeInsets.only(
                    bottom: MediaQuery.of(context).viewInsets.bottom),
                child: TextField(
                  decoration: InputDecoration(
                    hintText: 'adddrss'
                  ),
                  autofocus: true,
                  controller: _newMediaLinkAddressController,
                ),
              ),

              SizedBox(height: 10),
            ],
          ),
    ));

Please note that:

shape: RoundedRectangleBorder(
        borderRadius: BorderRadius.vertical(top: Radius.circular(25.0))),

It's not required. It's just that I'm creating a rounded bottom sheet.

padding: MediaQuery.of(context).viewInsets

UPDATED Flutter 2.2 breaks the changes again!” Now you need to give bottom padding once again so keyboard don't overlaps bottomsheet.

Just add:

• isScrollControlled: true to showModalBottomSheet
• padding: MediaQuery.of(context).viewInsets to widget in builder
• column/wrap both works

showModalBottomSheet<void>(
  isScrollControlled: true,
  context: context,
  shape: RoundedRectangleBorder(
    borderRadius: BorderRadius.only(
        topLeft: Radius.circular(30.0),
        topRight: Radius.circular(30.0)),
  ),
  builder: (BuildContext context) {
    return Padding(
        padding: MediaQuery.of(context).viewInsets,
        child: Container(
            child: Wrap(
          children: <Widget>[
            TextField(
              decoration: InputDecoration(
                  border: InputBorder.none,
                  hintText: 'Enter a search term'),
            ),
            TextField(
              decoration: InputDecoration(
                  border: InputBorder.none,
                  hintText: 'Enter a search term'),
            ),
            TextField(
              decoration: InputDecoration(
                  border: InputBorder.none,
                  hintText: 'Enter a search term'),
            ),
            TextField(
              decoration: InputDecoration(
                  border: InputBorder.none,
                  hintText: 'Enter a search term'),
            )
          ],
        )));
  },
);

Update Feb 25 2020 better solution

showModalBottomSheet(
 isScrollControlled: true,
 builder: (BuildContext context) {

    return SingleChildScrollView(
      child: Container(
        padding:
            EdgeInsets.only(bottom: MediaQuery.of(context).viewInsets.bottom),
        child: Padding(
          padding: const EdgeInsets.fromLTRB(20.0, 20.0, 20.0, 0.0), // content padding
          child: Form(...)) // From with TextField inside


});

In Order to focus on the Keyboard in BottomSheet - Wrap TextField in Padding Widget as like Below e.g Code:

showModalBottomSheet(
              context: context,
              builder: (context) {
                return Container(
                  child: Padding(
                    padding: EdgeInsets.only(
                        bottom: MediaQuery.of(context).viewInsets.bottom),
                    child: TextField(
                      autofocus: true,
                    ),
                  ),
                );
              }); 

In the latest version of flutter, you can move your bottomSheet using isScrollControlled property/named parameter. Suppose i have a function(_showModal) which will invoke when a button is pressed. And i define the bottom sheet functionality on that function.

void _showModal() {
  showModalBottomSheet(
    isScrollControlled: true,
    context: context,
    builder: (BuildContext context) {
      return Column(
        children: <Widget>[
          TextField(// your other code),
          SizedBox(height: 5.0),
          TextField(// your other code),
          SizedBox(height: 5.0),
          TextField(// your other code),
        ]
      );
    },
  );
}

Here a ModalBottomSheet will appear but with fullscreen of height. And you don't need that height. So, you need to Column's mainAxisSize to min.

Column(
  mainAxisSize: MainAxisSize.min,
  // your other code
)

Fullscreen of height problem is solved, but ModalBottomSheet doesn't move to top when keyboard is appeared. Ok, to solve this issue you need to set viewInsets bottom padding to your ModalBottomSheet. So to set padding we need to wrap our Column with Container or Padding and then set the padding. The final code will look like this

void _showModal() {
  showModalBottomSheet(
    isScrollControlled: true,
    context: context,
    builder: (BuildContext context) {
      return Container(
        padding: EdgeInsets.only(
          bottom: MediaQuery.of(context).viewInsets.bottom,
        ),
        // You can wrap this Column with Padding of 8.0 for better design
        child: Column(
          mainAxisSize: MainAxisSize.min,
          children: <Widget>[
            TextField(// your other code),
            SizedBox(height: 5.0),
            TextField(// your other code),
            SizedBox(height: 5.0),
            TextField(// your other code),
          ]
        ),
      );
    },
  );
}

Hope your issue is fixed. Thank's 🙏

I got it fixed by increasing the height of the child widget when the keyboard gets opened. initially value of MediaQuery.of(context).viewInsets.bottom will be 0 it will change when the keyboard gets focused.

showModalBottomSheet<void>(
      enableDrag: true,
      isScrollControlled: true,
      context: context,
      builder: (BuildContext context) {
        return Card(
          color: Colors.white,
          child: Container(
            height: MediaQuery.of(context).size.height / 2 +
                MediaQuery.of(context).viewInsets.bottom,
            child: Column(
              children: <Widget>[
                TextField(),
                TextField(),
              ],
            ),
          ),
        );
      },
    );

Try this

My Solution is

• Use isScrollControlled: true
• Add Padding

  padding: EdgeInsets.only(bottom: MediaQuery.of(context).viewInsets.bottom)
  

• Wrap your layout in SingleChildScrollView

SAMPLE CODE

Future<void> future = showModalBottomSheet(
  context: context,
  isDismissible: true,
  isScrollControlled: true,
  backgroundColor: Colors.white.withOpacity(0.2),
  builder: (context) => SingleChildScrollView(
    child: GestureDetector(
      child: Padding(
        padding: EdgeInsets.only(
          bottom: MediaQuery.of(context).viewInsets.bottom
        ),
        child: Container(
          width: MediaQuery.of(context).size.width,
          height: MediaQuery.of(context).size.height,
          child: Column(
            children: <Widget>[
              // add your widget here
            ],
          ),
        ),
      )
    ),
  )
);
