Research direction

Start with src/components/TextInput/hooks.ts and TextInput.tsx:401, where animatedContainerStyle is applied to the native input wrapper. Check how opacity depends on whether a label is present, then add or adapt a test for an empty, unfocused TextInput without a label. Done when its placeholder is visible while the labeled input keeps its floating-label behavior.

Description

bug
Current behaviour

A TextInput with no label is invisible while it is empty and unfocused: its input, its placeholder and any prefix or suffix have opacity 0, so only the outline shows until the field is focused. The wrapper around the native input takes the label float opacity (animatedContainerStyle in src/components/TextInput/hooks.ts, applied at TextInput.tsx:401) whether or not there is a label, and that value is 0 while the field is empty and unfocused. In 5.x the placeholder was visible.

Expected behaviour

A TextInput without a label shows its input and placeholder at full opacity at all times. Only a TextInput with a label hides the input while the label rests in its place.

How to reproduce?
const [query, setQuery] = React.useState('');

<TextInput
  variant="outlined"
  placeholder="Search for plugins..."
  value={query}
  onChangeText={setQuery}
/>
  1. Render it: only the outline shows, with no placeholder.
  2. In a test, expect(screen.getByPlaceholderText('Search for plugins...')).toBeVisible() fails with "Received element is not visible".
What have you tried so far?

Applying animatedContainerStyle only when label is set keeps the floating label behaviour and shows the placeholder.
