When I click on the text field, the second text field becomes very small

CodePudding user response：

Change the flex value of first expanded widget to 1 instead of 0.

Edit

Remove expanded from both the widgets. In first text field add maxLines : 1 and in second textfield add maxLines : null.

CodePudding user response：

Remove Expanded Widgets from both TextField and Wrap main Column to SingleChildScrollView to avoid getting overFlow errors
