If I were to create a multiplatform mobile app today, I would strongly consider using **Flutter** with **Dart** as the programming language. Here's why:

### 1. **Cross-Platform Consistency**
   - **Flutter** allows for a single codebase that can be deployed across multiple platforms (iOS, Android, Web, Desktop). This significantly reduces development time and ensures consistency across platforms.

### 2. **Performance**
   - **Flutter** is known for near-native performance. Unlike some other frameworks, it doesn't rely on a JavaScript bridge (like React Native), which results in faster execution and smoother animations.

### 3. **UI Flexibility and Customization**
   - **Flutter** provides a rich set of customizable widgets that allow developers to create highly tailored UIs. This is particularly useful when you need a custom and polished user interface.

### 4. **Growing Ecosystem and Community Support**
   - **Flutter** has seen rapid growth and adoption, backed by Google. The ecosystem is expanding with a wide range of plugins and packages, and the community is active, meaning you're likely to find support and resources for most challenges.

### 5. **Dart as a Language**
   - **Dart** is a relatively easy language to pick up, especially if you're familiar with languages like JavaScript, Java, or C#. It’s also designed to be performant for UI development.

### 6. **Hot Reload**
   - **Flutter's** hot reload feature speeds up the development process by allowing developers to see the results of their code changes in real time without needing to rebuild the app.

### 7. **Integration and Deployment**
   - **Flutter** integrates well with CI/CD pipelines and has good support for automated testing. The framework also makes it easy to package and deploy apps on multiple platforms.

### Alternative: **React Native**
If you or your team are more experienced with JavaScript/TypeScript and want to leverage the extensive ecosystem of JavaScript libraries, **React Native** is a viable alternative
