react-native-camera

问题 I have tried many attempts to get react-native-image-picker up and working with my RN app. I am using Expo and VS Code and am not running the app with Xcode or Android Studio. There seems to be many options to getting the camera roll available in an app and I am not sure which is the best path to take. None seem to be working for me so I would like to pick the best path and focus on making that one route work. I am following the documentation: https://github.com/react-native-community/react

问题 takePicture = async function() { if (this.camera) { const options = { quality: 0.5, base64: true, mirrorImage: true }; const data = await this.camera.takePictureAsync(options) this.setState({path: data.uri}) } } takePicture is the function to capture the image. Now I want to save the captured image and upload it to Firebase storage. this.setState({path: data.uri}) updates the path to clicked Image's location. How do I use react native fetch blob to upload my image in firebase storage? Please

I can't seem to find any information on getting the front
