Add DT Exchange to GDPR and US state regulations ad partners list

Step 3: Import the DT Exchange SDK and adapter
Integration through pub.dev
Add the following dependency with the latest versions of the
DT Exchange SDK and adapter in your
package's pubspec.yaml file:
dependencies:
gma_mediation_dtexchange: ^1.0.0
Manual Integration
Download the latest version of Google Mobile Ads mediation plugin for
DT Exchange,
extract the downloaded file, and add the extracted plugin folder
(and its contents) to your Flutter project. Then, reference the plugin in your
pubspec.yaml file by adding the following dependency:
dependencies:
gma_mediation_dtexchange:
path: path/to/local/package
Step 4: Implement privacy settings on DT Exchange SDK
EU Consent and GDPR
Under the Google EU User Consent Policy, you must ensure that certain disclosures are given to, and consents obtained from, users in the European Economic Area (EEA) regarding the use of device identifiers and personal data. This policy reflects the requirements of the EU ePrivacy Directive and the General Data Protection Regulation (GDPR). When seeking consent, you must identify each ad network in your mediation chain that may collect, receive, or use personal data and provide information about each network's use. Google currently is unable to pass the user's consent choice to such networks automatically.
The Google Mobile Ads mediation plugin for DT Exchange does not support passing consent information to the DT Exchange SDK.
US states privacy laws
US states privacy laws require giving users the right to opt out of the "sale" of their "personal information" (as the law defines those terms), with the opt-out offered through a prominent "Do Not Sell My Personal Information" link on the "selling" party's homepage. The US states privacy laws compliance guide offers the ability to enable restricted data processing for Google ad serving, but Google is unable to apply this setting to each ad network in your mediation chain. Therefore, you must identify each ad network in your mediation chain that may participate in the sale of personal information and follow guidance from each of those networks to ensure compliance.
The Google Mobile Ads mediation plugin for DT Exchange does not support passing consent information to the DT Exchange SDK.
Step 5: Add required code
Android
No additional code is required for DT Exchange integration.
iOS
SKAdNetwork integration
Follow DT Exchange's
documentation
to add the SKAdNetwork identifiers to your project's Info.plist file.
Step 6: Test your implementation
Enable test ads
Make sure you register your test device for Ad Manager.
Verify test ads
To verify that you are receiving test ads from DT Exchange, enable single ad source testing in ad inspector using the DT Exchange (Waterfall) ad source(s).
Error codes
If the adapter fails to receive an ad from DT Exchange, publishers can check the
underlying error from the ad response using
ResponseInfo under the
following class:
