Fork this project. 16 | 2. Create a new branch named `custom-{write-your-implementation-name}`. 17 | 3. Create a new picker dart file named `{your_implementation_name}_asset_picker.dart` in the `pickers` folder. 18 | 4. Brought all your implementations into the file you've just created. 19 | 5. Add a `CustomPickMethod` at the `custom_picker_page.dart` file in `pickMethods` 20 | in order to build an entrance to your picker. 21 | 6.
