I have a textfield that crashes when I select the textfield to enter text. no keyboard appears and app crashes. Happens on iphones, textfield works fine on iPad.

SizedBox(
  width: 140,
  height: 38,
  child: TextField(),
);

Here is the textfield I used to resolve the issue I posted above.

SizedBox(
      width: 180,
      height: 28,
      child: ClipRRect(
        borderRadius: BorderRadius.circular(14),
        child: TextField(
          textAlign: TextAlign.center,
          onChanged: (searchTerm) => bloc(context).add(SearchEvent(searchTerm)),
          onEditingComplete: () => bloc(context).add(SearchEvent('')),
          onSubmitted: null, //do nothing
          decoration: InputDecoration(
            hintStyle: textStyle,
            labelStyle: textStyle,
            fillColor: Colors.white,
            filled: true,
            border: InputBorder.none,
            hintText: 'Enter search terms',
          ),
        ),
      ),
    );
