Pull request overview

This PR updates the Android/Material implementation of AdaptiveButton to better align with Material 3 by using a FilledButton for the “filled” style, but it also includes a number of accidentally committed Gradle build/cache artifacts under android/ that should be removed before merging.

Changes:

• Switch AdaptiveButtonStyle.filled on Material to use FilledButton (Material 3) instead of ElevatedButton.
• Minor formatting change to Cupertino button padding.
• (Unintended) Adds generated Gradle report/cache files under android/build/ and android/.gradle/.

• There are widget tests for AdaptiveButton, but none assert that the filled style renders the intended Material3 FilledButton. Adding an assertion (e.g., that AdaptiveButton(style: filled) builds a FilledButton) would prevent regressions back to ElevatedButton and ensure the Material3 change is covered.

      case AdaptiveButtonStyle.filled:
        // Use theme's ElevatedButton style and only override explicitly provided values
        return FilledButton(
          onPressed: effectiveOnPressed,
          style: FilledButton.styleFrom(
            backgroundColor: color, // null = use theme
            foregroundColor: textColor, // null = use theme
            padding: padding, // null = use theme
            minimumSize: minSize, // null = use theme
            shape: borderRadius != null
                ? RoundedRectangleBorder(borderRadius: borderRadius!)
                : null, // null = use theme
          ),
          child: buttonChild,
        );

The inline comment says this branch uses the theme's ElevatedButton style, but the implementation now returns a FilledButton. Update the comment to match the actual widget/theme being used to avoid misleading future maintenance.

Suggested change

	// Use theme's ElevatedButton style and only override explicitly provided values
	// Use theme's FilledButton style and only override explicitly provided values

Gradle buildOutputCleanup cache metadata is generated during local builds and should not be tracked. Remove it from the PR and ignore android/.gradle/ (or **/.gradle/).

This appears to be a generated Gradle build report (android/build/...). Build outputs should not be committed to source control; please remove this file from the PR and add an ignore rule (e.g., android/build/ or **/build/) so it won't be re-added.

Hello, thank you for your support. However, as Copilot stated, it appears that files that shouldn't have been sent have been sent. Could you please remove these files? Thank you.
