[Bug]: TermsAndConditionsUIParams.mainTextColor does not apply to all text elements in consent dialog

[IvelinKrastev]

Is there an existing issue for this?

• I have searched the existing issues

Description of the bug

When using GoogleMapsNavigator.showTermsAndConditionsDialog() with custom TermsAndConditionsUIParams, the **mainTextColor** parameter does not apply to all text elements. Certain body text sections remain in a hardcoded color (black) rather than using the provided mainTextColor.

Flutter version

3.38.7

Package version

0.8.2

Steps to reproduce

1. Create a Flutter app with google_navigation_flutter package
2. Configure dark-themed TermsAndConditionsUIParams (see code sample below)
3. Call GoogleMapsNavigator.showTermsAndConditionsDialog() with the params
4. Observe the consent dialog - some text is invisible (black on dark background)

Expected vs Actual Behavior

Expected Behavior

All body text in the terms and conditions dialog should use the mainTextColor (white in this example).

Actual Behavior

Only some text elements use mainTextColor. The following sections remain black, making them invisible on a dark background:

• "How navigation data is used" section header and body
• "When you use [App] Ltd., Google collects..." paragraph
• "These updates to the map won't be associated..." paragraph
• "How driver reports and edits are used" section header and body

Code Sample

final uiParams = TermsAndConditionsUIParams(
  backgroundColor: Colors.black,
  titleColor: Colors.white,
  mainTextColor: Colors.white,  // Should apply to all body text
  acceptButtonTextColor: Colors.blue,
  cancelButtonTextColor: Colors.grey,
);

await GoogleMapsNavigator.showTermsAndConditionsDialog(
  'App Title',
  'Company Name',
  uiParams: uiParams,
);

Hey @IvelinKrastev and thanks for opening the issue.

I was able to reproduce this on Android but it's working fine on iOS so I believe we have a bug here. That being said we are passing the value correctly to the native side but not all the labels are being colored with the selected mainText color. This is a native SDK issue and I suggest you open issue in the Android Navigation SDK issue tracker:
