This error indicates a dependency conflict between your Flutter SDK's `flutter_test` package and the `video_totext` package in your FlutterFlow project. * `flutter_test` (from your Flutter SDK) requires `collection 1.19.0`. * `video_totext` (a package in your project) requires `collection 1.19.1`.

This mismatch prevents `pub` from resolving the dependencies, leading to the \"version solving failed\" error. Here's how you can troubleshoot and resolve this, based on common solutions for `collection` package conflicts in FlutterFlow projects: 1. **Update FlutterFlow Desktop Application (If using Local Run):** If you are encountering this error when running your project locally via the FlutterFlow desktop application, this type of `collection` conflict has been identified as a known issue (e.g., GitHub issue #5409).

A fix was released in subsequent desktop application updates. * Ensure your FlutterFlow desktop application is updated to the latest available version. Sometimes, repeatedly clicking the \"update flutter\" button within the local run setup wizard in the desktop app can trigger the update process if it seems unresponsive initially.

2. **Match Your Local Flutter SDK Version:** A common cause for such conflicts when running locally is a mismatch between your local Flutter SDK version and the version FlutterFlow uses or recommends. The context specifically mentions that downgrading the local Flutter SDK version to **3.24.2** was a suggested step to resolve a `collection` 1.19.0 vs 1.19.1 conflict for local runs.

* **Check your current Flutter version:** Open your terminal and run `flutter --version`. * **Downgrade/Switch Flutter version:** If your version is different, you might need to switch to a compatible version. You can use `fvm` (Flutter Version Manager) for easier switching, or manually download specific SDK versions from the [Flutter Archives](https://docs.flutter.dev/sdk/releases/archive) and set it up as your active version.

Example command to switch: ```bash flutter version v3.24.2 ``` * After changing the Flutter version, run `flutter clean` and then `flutter pub get` in your project directory. 3. **Override `collection` Dependency (for downloaded code):** If you have downloaded your project's code, you can explicitly override the `collection` package version in your `pubspec.yaml` file to satisfy the `flutter_test` requirement.

Since `flutter_test` is from the SDK and requires `1.19.0`, you would typically try to force `collection` to `1.19.0` and hope `video_totext` can tolerate it. * **Download Project Code:** If you haven't already, download the source code of your FlutterFlow project. * **Locate `pubspec.yaml`:** Open the downloaded project folder in a code editor and find the `pubspec.yaml` file at the root.

* **Add `dependency_overrides`:** Add the following section to your `pubspec.yaml` file: ```yaml dependency_overrides: collection: 1.19.0 ``` * **Save and Run `flutter pub get`:** Save the changes to `pubspec.yaml`. Open a terminal, navigate to your project's root directory, and run: ```bash flutter pub get ``` * **Alternatively, use `flutter pub add`:** You can also try to add or update the `collection` dependency directly from the terminal (this modifies `pubspec.yaml` and runs `pub get`): ```bash flutter pub add collection:^1.19.0 ``` Note: This might not be ideal if `video_totext` strictly requires `1.19.1` and cannot function with `1.19.0`. 4.

**Update Packages within FlutterFlow (if applicable):** If you are working within the FlutterFlow web interface, ensure all packages are updated. * Go to **Settings** > **Packages** and click **Update All Packages**. 5.

**Clean Build Cache:** After making any changes to your Flutter SDK version or `pubspec.yaml`, always clean your project's build cache and fetch dependencies again. * In your project directory, run: ```bash flutter clean flutter pub get ``` By trying these steps, you should be able to resolve the dependency conflict and successfully update your packages or run your project.
