Question

I have problem with flutter textformfield. Like I said in title my app show cursor in two textformfield. It appear when I tap previous textfield. I'm using real phone for test, not tried in emulator. Thanks for any help.
Here image from my app:
enter image description here
Form(
key: _formKey,
child: Column(
children: <Widget>[
SizedBox(
height: 20.0,
),
TextFormField(
decoration: InputDecoration(labelText: 'Email'),
focusNode: _emailFocus,
onFieldSubmitted: (term) {
_passwordFocus.nextFocus();
_fieldFocusChange(
context, _emailFocus, _passwordFocus);
},
textInputAction: TextInputAction.next,
validator: (value) =>
value.isEmpty ? 'Enter an email' : null,
onChanged: (value) {
setState(() => email = value);
},
),
SizedBox(
height: 20.0,
),
TextFormField(
decoration: InputDecoration(labelText: 'Password'),
validator: (value) => value.length < 6
? 'Enter an password 6+ chars long'
: null,
obscureText: true,
focusNode: _passwordFocus,
onFieldSubmitted: (term) {
_passwordFocus.unfocus();
_submitForm();
},
textInputAction: TextInputAction.done,
onChanged: (value) {
setState(() => password = value);
},
),
SizedBox(
height: 20.0,
),
RaisedButton(
color: Theme.of(context).primaryColor,
child: Text('Sign in'),
onPressed: () {
_submitForm();
},
),
SizedBox(height: 12.0),
Text(error,
style:
TextStyle(color: Colors.red, fontSize: 14.0)),
],
)),

I found solution from this question:
Multiple cursor in form's TextFormField flutter
It is same as mine. We did same mistake. When I declare FocusNode global it solve problem.
