GlassFormField class

A standard form field wrapper for glass inputs following iOS design patterns.

GlassFormField wraps input widgets (like GlassTextField, GlassPicker, etc.) with a standard label, error text, and helper text layout. It ensures consistent spacing and typography across all form inputs in an application.

Key Features

  • Consistent Typography: Uses standard iOS-style weights and colors for labels
  • Validation Support: Displays error text in red when provided
  • Helper Text: Optional secondary text for hints or instructions
  • Flexible Layout: Works with any child widget

Usage

Basic Usage

GlassFormField(
  label: 'Email Address',
  child: GlassTextField(

)

With Validation Error

GlassFormField(
  label: 'Password',
  errorText: isPasswordValid ? null : 'Password must be at least 8 chars',
  child: GlassPasswordField(),
)

With Helper Text

GlassFormField(
  label: 'Username',
  helperText: 'This will be visible to other users',
