So I spent two days writing a garbage App, using the Flutter as a development framework that supports both iOS & Android. Currently App is relatively simple, can see all the garbage classification in that category by clicking on a specific trash, garbage is also supported for text search.
Search API interfaces using the official Shanghai Greening and City Appearance Administration, the accuracy of the results obtained is relatively high, I can not tell my mother no longer have to worry about garbage friends.
technical details
Basically no technical details. . . With the provider to do data binding status and management, in addition Json data garbage is relatively large, so do a cache After each request after the data is written to a local file.
Then will consider joining the "Guess" feature allows users to identify spam given what kind of garbage belongs.
Apple Developer account expired. . . We might first look, made an Android version.
Then probably write a SwiftUI version. . .

Digression beyond technology
Garbage is actually very difficult, the United States today are not ready, we can see how much of China's difficulties. There will be growing pains, a lot of people will complain about why so strict policy never to do so. In fact, when you really get to know these countries, Japan and South Korea garbage do well, we can only lament the current policy is not enough absolutely! Japan and South Korea on the road is fundamentally no trash, that is, after the implementation of waste trade-offs results. why? Because as long as there is an unregulated trash, no one is willing to take the initiative to do and then thrown into the garbage in the correct position within the stipulated time. Garbage classification policy is a policy must not be soft-hearted, because once ambiguous, it will immediately become useless vanity project.
China is recycled material production and consumption country, there are plenty of companies willing to receive garbage compliant renewable let them waste to treasure. But before Since China has failed to implement waste separation policy in the true sense, domestic enterprises have to beg for trash to overseas countries. This is not only a detour of elbow grease, leaving China suffered different degrees of pollution. China and some developing countries have jointly announced that it no longer receives garbage imports of developed countries, we can achieve self-sufficiency in the renewable industry.
