    filterType: 1,
  },
  (source) => {
    this.setState((imgBase64: source.base64));
    console.log("SOURCE", source);

Options

Props	Default	Options/Info
imageSource (String)	null	The path to the image in the device or a Base64 string.
dataType (String)	Path	If you send a path, enter the string "Path" If you send a Base64 string, enter the string "Base64".
filterType (int)	0	Select the type you want to filter images, the values from 0 to 21. Other values around 0 to 21 will not take effect. Note: Valid only when dataType = "Path".

Filter types

Note

• The image path you send into imageSource:'' must be the absolute path. If you have problems with the absolute path, you can find the solution here.
