ShowModalBottomSheet containing Textfield gets hidden with keyboard following Flutter upgrade 2.2.0

Question

In my app, when user clicks on FAB, it triggers a ModalBottomSheet which contains a textfield. Up until today (when I updated to flutter 2.2.0), the code below worked fine : when user tapped the textfield, the BottomSheet moved up and we could use the keyboard fine. Now, when we tap the textfield, the keyboard hides the BottomSheet.

Has there been a change with the update ?

Here is the code :

floatingActionButton: FloatingActionButton(
          backgroundColor: Colors.blue[800],
          child: Icon(Icons.add),
          onPressed: () {
            showModalBottomSheet<void>(
              isScrollControlled: true,
              shape: RoundedRectangleBorder(
                borderRadius: BorderRadius.only(
                  topLeft: Radius.circular(20.0),
                  topRight: Radius.circular(20.0),
                ),
              ),
              context: context,
              builder: (BuildContext context) {
                return Container(
                  height: 250,
                  child: Center(
                    child: Column(
                      mainAxisSize: MainAxisSize.min,
                      mainAxisAlignment: MainAxisAlignment.center,
                      children: <Widget>[
                        Padding(
                          padding: const EdgeInsets.all(26.0),
                          child: Column(
                            crossAxisAlignment: CrossAxisAlignment.stretch,
                            children: [
                              Padding(
                                padding: const EdgeInsets.only(top: 8.0),
                                child: Text(
                                  'Ajouter une liste au carnet',
                                  textAlign: TextAlign.center,
                                  style: TextStyle(
                                    color: Colors.blue[800],
                                    fontSize: 22.0,
                                  ),
                                ),
                              ),
                              SizedBox(
                                height: 30,
                              ),
                              Column(
                                children: [
                                  TextFormField(
                                    keyboardType: TextInputType.emailAddress,
                                    decoration: InputDecoration(
                                        focusColor: Colors.blue,
                                        border: OutlineInputBorder(
                                          borderRadius:
                                              BorderRadius.circular(10.0),
                                        ),
                                        labelText:
                                            'Titre de la nouvelle liste'),
                                    onChanged: (value) {
                                      titre = value;
                                    },
                                  ),
                

Solution

I found a way to solve this : I added SingleChildScrollView as the first Child to ModalBottomSheet and added the padding element given by "CbL" directly there and not to the container.

 return SingleChildScrollView(
                  padding: EdgeInsets.only(
                      bottom: MediaQuery.of(context).viewInsets.bottom),
                  child: Container(
                    height: 250,

Thanks CbL for your help :)
