There are few workarounds for this. To know more use this as reference: https://github.com/flutter/flutter/issues/19488

prefixIcon: Row(
                    mainAxisSize: MainAxisSize.min,
                    children: <Widget>[
                    Padding(
                      padding: EdgeInsets.symmetric(horizontal: 10),
                      child: Text('Subject:',style: TextStyle(color: Colors.black),),
                    )
                  ],),
                  hintText: "Unique Subject",
                  border: OutlineInputBorder(),
